Al-Maturidi (853-944)

Mâturîd, a District on the Farthest Frontier of Islam

Al-Mâturîdî was born in the district of Mâturîd (or Mâturît), on the outskirts of Samarkand, then one of the principal metropolises of Transoxiana — that region of Central Asia beyond the Oxus (the present-day Amu Darya), corresponding largely to modern Uzbekistan^[5]. His nisba (geographical surname) alone establishes his origin: he lived in Samarkand all his life and died there, according to the unanimous consensus of the sources, in 333 AH (944)^[6].

The date of his birth, by contrast, remains uncertain — a gap that the Orientalist tradition long filled with the conventional date of 238 AH (852–853), still the most cited today. Ulrich Rudolph, in his critical study of the biographical sources, observes however that no ancient source gives this date, and that it actually rests on an indirect reconstruction: examining the chronology of his teachers — one of whom died on a military campaign against the Turks around 890 — Rudolph considers it more prudent to place his birth around 870, if not slightly earlier, which would make him a noticeably younger man at his death than is generally assumed^[7]. Ignispedia reports this uncertainty without deciding: the date "853–944" used in the title of this article follows the received tradition, the most widely disseminated in contemporary encyclopaedias, but the demanding reader should know that it rests on more fragile foundations than it appears.

"The Great Unknown": A Life Without Anecdote

Unlike al-Ash'ari — whose biographical tradition preserves the spectacular scene of his public break in the middle of the Basra mosque — al-Mâturîdî leaves his biographers almost no narrative material. Rudolph states this with a frankness worth quoting in full:

"Abû Mansûr Muhammad b. Muhammad b. Mahmûd al-Mâturîdî, if one is willing to believe the rare reports transmitted about him, led a life notable in no way, nor different from that of his learned contemporaries in Samarkand. There is no indication that he held public office, nor that he had more disciples, popularity, or even connections with the Samanid court of Bukhara than anyone else." — Ulrich Rudolph, Al-Māturīdī and the Development of Sunnī Theology in Samarqand, Leiden-Boston, Brill, "Islamic History and Civilization" series, vol. 100, 2015, p. 125^[8]

No spectacular conversion, no trial, no exile, no persecution: the surviving sources — essentially the late testimony of Abû l-Mu'în al-Nasafî (d. 508 AH / 1114) in his Tabsirat al-adilla, and the brief eulogy of Abû l-Yusr al-Pazdawî (d. 493 AH / 1100) in his Usûl al-dîn — are limited to lists of works accompanied by a few words of theological praise^[9]. Even the exact date of his death is unknown: al-Nasafî merely says that he died "shortly after al-Ash'ari" (d. 324 AH / 935–936), which is nevertheless sufficient, cross-checked with other sources, to establish a near-unanimous consensus on the year 333 AH (944)^[10].

The only slightly personal biographical touches concern his reputation as an ascetic (zâhid), to which a family tradition transmitted by al-Pazdawî adds even a few miracles (karâmât)^[11]. Rudolph takes care, however, to rule out any hasty assimilation to Sufism: none of his extant works addresses the themes typical of Muslim mysticism — trust in God, spiritual scrupulousness, methodical asceticism — and his name appears in no later Sufi biographical compilation^[12]. Al-Mâturîdî remains, from one end of his documented life to the other, a man of kalâm, not a mystic.

Abû Bakr al-Jûzjânî: Hanafi Piety and Law

Al-Mâturîdî received his training from two Samarkandi teachers, whose profiles complement each other in a revealing way. The first, Abû Bakr Ahmad al-Jûzjânî, was a versatile Hanafi jurist, competent both in the principles (usûl) and in the concrete applications (furû') of the law, author of a legal treatise — the Kitâb al-Farq wa-l-tamyîz — and of a now-lost work of piety, the Kitâb al-Tawba ("Book of Repentance")^[13]. Nothing indicates that al-Jûzjânî practised kalâm in the technical sense of the term: he transmitted Hanafi law and a traditional teaching of piety to his pupil, not an already constituted speculative theology^[14].

Abû Nasr al-'Iyâdî: First Theologian of Eastern Kalâm

The second teacher, Abû Nasr Ahmad al-'Iyâdî, brings an entirely different dimension to al-Mâturîdî: himself also a disciple of al-Jûzjânî, he stands out as a theologian in his own right, author of a treatise — now lost — devoted to the divine attributes, in which he explicitly refuted the Mu'tazilite positions and those of the theologian al-Najjâr^[15]. Biographical tradition remembers al-'Iyâdî for a heroic death: taken prisoner during a military expedition of the Samanid emir Nasr ibn Ahmad against the Turks, he died a martyr at the hands of the enemy, an episode that explains the particular veneration he enjoys in Samarkandi memory^[16]. Rudolph observes that this treatise on the divine attributes may well constitute the earliest known example of Eastern Hanafi kalâm — which would make al-'Iyâdî not the founder of a school, but the direct model on whom al-Mâturîdî drew to build, a generation later, a theology of unprecedented scope and technical sophistication within the Hanafi tradition of Transoxiana^[17].

The Kitâb al-Tawhîd, a preserved doctrinal summa

Al-Mâturîdî's principal work to have come down to us is the Kitâb al-Tawhîd ("Book of divine unity"), a theological summa divided into two large parts: the first devoted to epistemology, the structure of the world, and the demonstration of God's existence and attributes; the second concerned with human action, the nature of faith, and the fate of the sinner^[18]. It is a work of combat as much as of synthesis: in it he methodically refutes the positions of the Mu'tazilites, the Qarmatians, the Manichaean dualists, the "sophists", the Christians, and the sect of the Karrâmites, while building, chapter after chapter, his own Hanafite doctrine of divine unity^[19]. The work is remarkable for the genuine theory of knowledge (epistemology) that it sets out systematically from its very first chapters, making it one of the most complete sources of classical kalâm on this point^[20].

The Ta'wîlât al-Qur'ân, a rational Qur'anic commentary

The second pillar of his preserved oeuvre, the Ta'wîlât al-Qur'ân — also called the Ta'wîlât ahl al-sunna ("Interpretations of the people of the Sunna") — is a complete Qur'anic commentary that systematically applies the rational method of kalâm to the theological and legal verses of the Qur'an^[21]. Long known only through partial manuscripts and fragmentary editions, this commentary first appeared in its entirety in Beirut in 2004, in Fâtima Yûsuf al-Khaymî's five-volume edition — established on only two manuscripts, hence non-critical; the critical reference edition, directed by Bekir Topaloğlu in Istanbul (eighteen volumes, 2005–2011), was not completed until 2011 — more than a thousand years after its composition, tangible proof of how slowly al-Mâturîdî's work became fully accessible even to modern scholars^[22].

The lost treatises against Mu'tazilites, Qarmatians and Shiites

The remainder of what was evidently a considerable output has disappeared almost in its entirety. All that is known, often only by their bare titles as cited in later bio-bibliographical literature, are works such as the Kitâb Bayân awhâm al-Mu'tazila ("Exposition of the errors of the Mu'tazilites"), the Kitâb Radd awâ'il al-adilla and the Radd al-tahdhîb fî l-jadal (two distinct refutations of Mu'tazilism), the Radd al-imâma (against the Shiite doctrine of the imamate), the Radd wa'îd al-fussâq (against the Mu'tazilite thesis of the eternal damnation of the grave sinner), the Radd 'alâ usûl al-Qarâmita (against Qarmatian doctrine), or the Radd al-usûl al-khamsa, a refutation of Abû 'Umar al-Bâhilî's exposition of the Mu'tazilite "five principles"^[23]. This mass of lost titles alone gives the measure of a considerable polemical activity, directed at almost every competing theological current of his time and region — Mu'tazilism, Shiism, Qarmatism, Manichaean dualism — of which, in the end, only the doctrinal framework preserved in the two major works that survived the centuries remains^[24].

Three paths of knowledge: the senses, transmission, the intellect

Al-Mâturîdî's most systematic contribution lies in his epistemology. He distinguishes three legitimate paths of access to knowledge: sense data (hiss), reliable transmission — the Qur'an, the prophetic tradition (sam') — and the intellect ('aql)^[25]. This threefold grid, which none of his Hanafite predecessors had formulated with such rigour, structures the whole of the Kitâb al-Tawhîd: each major thesis — God's existence, His unity, His attributes — is demonstrated there, as far as possible, by more than one of these three paths simultaneously, so as to convince both the rationalist theologian and the traditionist most wary of kalâm^[26].

Knowing God without revelation: the Hanafite rationalist wager

On one precise point, this epistemology clearly sets al-Mâturîdî apart from his contemporary al-Ash'ari. The question posed by classical kalâm is this: does the human being need the assistance of revelation to understand that creation testifies to a Creator, or is his intellect alone, by its own means, capable of it? Al-Ash'ari, while admitting that there are clear signs of God's existence, insisted that the human being first needed the stimulus of revelation even to become aware of the pressing question of a Creator's existence^[27]. Al-Mâturîdî rejects this restriction. He states without equivocation that there are two paths to knowledge of God: that of the prophets, and that of the rational observation of creation, the latter alone sufficing to establish, with certainty, the existence of a wise and unique Creator^[28].

This optimistic position, as Rudolph stresses, is not a mere concession to Mu'tazilite theses: it continues a rationalist tradition already present within the Hanafite school itself, attested as early as the school's founder. In his second epistle to 'Uthmân al-Battî, Abû Hanîfa already taught that God had created all men in such a way that they could, even before the revelation of the Qur'an, discern by themselves the path of obedience owed to Him^[29]. Al-Mâturîdî methodically develops this intuition into an unprecedented chapter devoted to the "indication of the unseen from the visible" (dalâlat al-shâhid 'alâ l-ghâ'ib), in which he takes care to distinguish legitimate inferences from misleading analogies between the created and the Creator, refusing in particular any naive analogia entis that would reduce God to the world He created^[30]. In the Kitâb al-Tawhîd, he thus justifies his method:

"The foundation of these arguments consists in that nothing is accomplished by Him [that is, by God] without a wisdom so admirable, and a sign so wondrous, that scholars are not capable of grasping their being and mode of existence." — Al-Mâturîdî, Kitâb al-Tawhîd, cited and translated into English by Ulrich Rudolph, Al-Māturīdī and the Development of Sunnī Theology in Samarqand, Brill, 2015, p. 263^[31]

The divine attributes: real, distinct, eternal

On the divine attributes — knowledge, power, life, speech, hearing, sight — al-Mâturîdî inherits and refines an already ancient Hanafite position, summarisable in three axioms: (1) God possesses attributes really distinct from His essence, not mere figures of speech; (2) these attributes, though bearing the same names as their human equivalents, must never be understood univocally with the latter, nor emptied of all meaning by a purely allegorical interpretation; (3) they are, without exception, eternal — whether attributes of essence (knowledge, power) or attributes of action (creation, speech)^[32]. It is precisely this third point that most clearly distinguishes the Hanafites — and hence al-Mâturîdî — from the Mu'tazilites, for whom God's attributes of action, such as creation, are necessarily temporal since they accompany acts genuinely accomplished in time^[33]. Al-Mâturîdî's principal theological adversary on this ground was the Mu'tazilite al-Ka'bî, whose school had just established itself in eastern Iran during his own lifetime, and whose thesis — nothing eternal can coexist with God — called into question the whole Hanafite edifice of the attributes^[34].

Takwîn: the creative act, an eternal attribute distinct from creation

It is in response to this challenge that al-Mâturîdî develops the most original and technically accomplished contribution of his theology: the doctrine of takwîn, the "act of creating". Against al-Ka'bî, who identified God's creative act (khalq) with its temporal result — the creature itself (makhlûq) — al-Mâturîdî insists on a decisive distinction: the verb is not the object. The act by which God creates is an eternal attribute of His being, distinct from the created things which, for their part, genuinely appear in time^[35]. God is thus Creator (mukawwin) from all eternity, even though the creatures themselves have existed only since a determinate moment — the technical formula adopted being that "God is described by the act of creating, from all eternity" (wusifa Allâhu bi-l-takwîn fî l-azal)^[36]. Al-Mâturîdî illustrates this thesis with a formula that has remained famous in the Maturidite tradition:

"God created in such a way that things exist, at a given moment, as they are" (kawwana li-tukawwana al-ashyâ'u 'alâ mâ takûnu). — Al-Mâturîdî, Kitâb al-Tawhîd, cited and translated into English by Ulrich Rudolph, op. cit., p. 286^[37]

The divine creative act, adds al-Mâturîdî, is accomplished neither by means nor by tools, unlike human action: God acts "by Himself" (bi-nafsihi), without effort, by the sole word "Be!" (kun)^[38]. This doctrine of takwîn would become, in the later controversy between Maturidites and Ash'arites, one of the most debated points of rupture — the Ash'arites holding, conversely, that the creative act (takwîn) is itself a temporal event and not a distinct eternal attribute^[39].

Bilâ kayfa: the throne, the vision of God and the ambiguous verses

A third classical difficulty of kalâm concerns the Qur'anic verses that describe God in concrete and potentially anthropomorphic terms — His "hand", His "face", His "throne" on which He "sits"^[40]. Al-Mâturîdî inherits here an already lively Hanafite controversy between, on the one hand, literalist traditionists such as the Karrâmite sect of Ibn Karrâm, who situated God concretely "above", in a determinate place, and on the other hand Mu'tazilites such as al-Ka'bî, who denied any localisation even metaphorical for fear of anthropomorphism^[41]. Al-Mâturîdî refuses both extremes: God, he affirms, is certainly not situated in a place, since He created places themselves and absolutely pre-exists them; but one must nevertheless believe what the Qur'an says, namely that God "sits" upon the throne, in a manner that entirely escapes our understanding^[42]. This is the systematic application of the principle known as bilâ kayfa ("without [asking] how"): affirming the revealed text without denying it by allegory, yet without ascribing to it an assignable corporeal modality either.

The same principle governs the question of the vision of God (ru'ya) in paradise, on which al-Mâturîdî directly opposes al-Ka'bî: against the Mu'tazilite denial, he maintains that believers will really see God in the afterlife — the Qur'an explicitly promises this on several occasions — while setting aside the idea that this vision would imply any "grasping" or "encompassing" (idrâk) of the divine essence by the human gaze, which would limit it to finite contours^[43]. Seeing is not necessarily understanding or circumscribing: the human eye, notes al-Mâturîdî, frequently perceives objects without thereby grasping their whole nature — an argument he turns against the univocal Mu'tazilite definition of "vision"^[44].

The two capacities to act: human freedom between nature and choice

On the question, as old as kalâm itself, of who — God or man — is the author of human acts, al-Mâturîdî takes up the classical Hanafite framework — derived from Abû Hanîfa himself — of a middle path between two heretical extremes: the "Jabrites", who deny any human share in action to the point of absolving man of all responsibility, and the "Qadarites", who on the contrary divinise the creature by attributing to it the full origination of its own acts^[45]. The Hanafite principle of compromise holds that God wills, decrees and creates every human action, but that man alone is its agent (fi'l) — receiving, in the case of a good action, divine assistance (tawfîq), and finding himself, in the case of a bad action, abandoned to himself (khidhlân)^[46].

Al-Mâturîdî's own contribution consists in specifying, with a subtlety attained by neither his Hanafite predecessors nor the Karrâmites, at what moment man receives the capacity (istitâ'a) to act. He in fact distinguishes two distinct capacities: a first, of a purely bodily nature — health, integrity of the limbs, normal use of the intellect — which precedes action and constitutes its mere precondition; a second, granted to man at the very moment of the act, which alone gives him the real possibility of choosing (ikhtiyâr) between two contrary actions, such as obeying or sinning^[47]. This distinction allows al-Mâturîdî to escape both the thoroughgoing determinism of the Karrâmites — for whom capacity exists integrally before the act — and the Qadarite or Mu'tazilite autonomy that would make man a second creator independent of God^[48]. Rudolph sums up the balance sought by this theory:

"The doctrine formulated by al-Mâturîdî aimed at establishing a balance and was intended to consolidate the middle position to which his school aspired." — Ulrich Rudolph, op. cit., p. 307^[49]

Faith: assent of the heart, neither increased nor diminished

On the nature of faith (îmân), al-Mâturîdî faithfully takes up the classical Hanafite definition, inherited from an ancient Murji'ite heritage going back to Abû Hanîfa himself: faith consists in the inner assent of the heart (tasdîq bi-l-qalb), accompanied by confession with the tongue (al-iqrâr bi-l-lisân), without works forming a constitutive part of it^[50]. Three consequences follow, which the Kitâb al-Tawhîd systematically defends against the Mu'tazilites and the Kharijites: (1) a believer who commits a grave sin remains a believer, against the Kharijites who at once make him an unbeliever, and against the Mu'tazilites who place him in an uncertain "intermediate position"^[51]; (2) the believing sinner, though he may be punished in hell for a time, will not remain there eternally — only unbelievers undergo endless damnation^[52]; (3) the Prophet's intercession on behalf of deceased sinners remains a legitimate hope, against the Mu'tazilites and Kharijites who deny it or restrict it to venial sins^[53].

Al-Mâturîdî further maintains, against the use of the so-called istithnâ' formula ("if God wills", added out of caution to the affirmation "I am a believer"), that the believer can and must affirm his faith without conditional reservation — a constant Hanafite position in the face of more sceptical traditionists^[54]. Finally, on a more technical question that divided the theologians of his time, he decides that faith itself, as a human act, is created (makhlûqa) — a position he defends with an argumentation of his own, without contenting himself, like some Hanafites of Bukhara, with a vague compromise on the subject^[55].

Reading the table: on the essentials of Sunni monotheism, the two schools converge very largely; their real technical divergences concern the precise articulation of reason and revelation, and the mechanics of the divine act and the human act. A broader comparative table, including Mu'tazilism and Hanbalite traditionalism, appears in the article Al-Ash'ari.^[56]

A generation with no declared posterity

The biographical paradox of al-Māturīdī continues, even more surprisingly, in the immediate history of his own school. Throughout the entire century following his death, no major Hanafi theologian of Transoxiana explicitly claimed his legacy. The only known text offering a faithful summary of his thought is the Jumal uṣūl al-dīn, the work of a second-rank disciple, Abū Salama al-Samarqandī, otherwise little known and probably active in the mid-4th/10th century^[57]. The most productive Hanafi of the next generation, Abū l-Layth al-Samarqandī (d. 373 AH / 983) — prolific author of Qur'anic commentaries, treatises of piety, and a famous collection, the Tanbīh al-ghāfilīn — never mentions al-Māturīdī in his own theological works, contenting himself with reproducing the standard Hanafi creed of the Kitāb al-Sawād al-aʿẓam^[58]. Rudolph draws a clear conclusion: properly Maturidi theology, however elaborate, simply had not yet gained broad recognition in Transoxiana by the end of the 4th/10th century, probably for lack of a sufficiently pressing theological adversary, Mu'tazilite or Ash'arite, to make it necessary^[59].

The irruption of Ash'arite rivalry in Transoxiana

The situation changed at the turn of the 5th/11th century, with the establishment of a conquering Ash'arism at Nishapur, in Khurasan, carried by theologians such as Ibn Fūrak (d. 406 AH / 1015) and al-Isfarā'inī (d. 418 AH / 1027)^[60]. It did not take long for the two schools to notice each other: by the middle of the 5th/11th century, the Ash'arite Abū Bakr al-Fūrakī (d. 478 AH / 1085) appears as the first explicit representative of Ash'arism in Transoxiana itself, while a local theologian, Abū Shakūr al-Sālimī, mentions the Ash'arites by name for the first time in a Hanafi work from the region^[61]. The climate between the two camps immediately became tense, the main point of friction being precisely whether the divine attributes of action — first and foremost takwīn — were to be held as eternal^[62]. A remarkable fact noted by Rudolph: at this stage still, neither camp mentions the name of al-Māturīdī in the controversy — the reference to his person remained, a century and a half after his death, entirely absent from the debate^[63].

Al-Pazdawī and al-Nasafī, the second founders

It is only in the third phase, at the very end of the 5th/11th century, that the name of al-Māturīdī reappears — and this time for good. Two Hanafi theologians, Abū l-Yusr al-Pazdawī and his junior Abū l-Muʿīn al-Nasafī, then elevate him, in the heat of the anti-Ash'arite controversy, into the decisive authority of the Transoxianian school^[64]. Al-Pazdawī defends the chronological anteriority of al-Māturīdī over al-Ash'ari himself on the thesis of the eternity of takwīn, asserting that al-Māturīdī "had already debated the Mu'tazilites on this controversial subject" and "had created nothing new," merely transmitting faithfully the ancient Hanafi theology^[65]. But it is al-Nasafī who goes furthest, in direct reaction to a grave accusation levelled by Ash'arite theologians: according to them, the Eastern Hanafi doctrine of takwīn was merely a recent heresy, forged after the year 400 of the Hijra (1010), with no support among the pious predecessors (al-salaf)^[66]. To refute this accusation, al-Nasafī sets out a long genealogy of Samarkandi theologians of the 2nd and 3rd centuries of the Hijra all professing, according to him, the eternity of the attributes of action — before concluding on al-Māturīdī himself with a formula that has remained famous:

"[However], had there been found among them the imam Abū Manṣūr al-Māturīdī, who plunged into the sea of knowledge to bring back its pearls… that would have sufficed. Whoever considers his achievements can only conclude that God distinguished him with miracles, gifts of grace, divine assistance and guidance." — Abū l-Muʿīn al-Nasafī, Tabṣirat al-adilla, vol. I, p. 358-359, quoted and translated into English by Ulrich Rudolph, op. cit., p. 322^[67]

Barely a few years after this reinterpretation, the theologian Najm al-Dīn al-Nasafī composed a creed faithfully reproducing the formulation of Abū l-Muʿīn — a creed that would become the standard reference of the school, still transmitted and commented upon today, under a name that was then still aṣḥāb Abī Ḥanīfa ("the partisans of Abū Ḥanīfa"), but which already designated, in reality, what would soon be called Maturidism^[68].

Two misleading images

Rudolph concludes his study by setting aside two simplifying images, both widespread in popular literature. The first presents al-Māturīdī as a mere faithful heir of Abū Ḥanīfa, transmitting the doctrine of the master of Kufa without adding much to it. This is inaccurate: while al-Māturīdī does indeed claim the authority of Abū Ḥanīfa, and while the Hanafis of Transoxiana retrospectively attributed to him, sometimes anachronistically, theological texts that the jurist of Kufa probably never wrote as such, a serious comparison between the authentic correspondence of Abū Ḥanīfa and the Kitāb al-Tawḥīd shows how far al-Māturīdī's thought evolved and deepened technically beyond its origins^[69].

The second image, even more widespread, makes him the mere Eastern counterpart of al-Ash'ari — two twin theologians each rediscovering, on their own side, the same Sunni orthodoxy. Rudolph judges this equally misleading: while real parallels do exist between the two men — contemporaneity, shared hostility to Mu'tazilism, foundation upon the Sunna — their respective intellectual approaches differ profoundly on almost every level, from epistemology to the conception of the world to human freedom^[70]. Rudolph approvingly quotes the characterisation offered by the Islamologist Daniel Gimaret: al-Ash'ari professes a theology of "vigorous, bold spirit," at times "brutally simplifying," whereas al-Māturīdī "aims at something slightly different," seeking a synthesis that does justice to as many divergent aspects as possible^[71]. The idea that the two schools professed, from the outset, essentially identical doctrines is, Rudolph concludes, "an illusion" born of a late harmonisation, motivated by classical Sunnism's concern to present a united theological front against its common adversaries — Mu'tazilism, Shi'ism, philosophy^[72].

Hanafism and Maturidism, two sister pillars

The geographical diffusion of Maturidism faithfully follows that of the Hanafi legal school to which it remains structurally bound, unlike Ash'arism, historically linked to the Shafi'i school^[73]. This solidarity between Hanafi law and Maturidi theology explains the remarkable geographical extension of the school: wherever Hanafism established itself as the dominant legal school — Central Asia, the Indian subcontinent, Anatolia, the Balkans, the Caucasus, western China — Maturidism eventually prevailed, if not always exclusively, at least as the reference theology of local religious elites^[74].

The official school of the Ottomans and the Mughals

Two great empires brought this diffusion to its peak. The Ottoman Empire, whose religious administration was organised around Hanafi law, adopted Maturidism as the official theology of the state, a status that endures today in the official doctrine of the Diyanet, the state religious authority of the Turkish Republic^[75]. The Mughal Empire, in India, likewise secured it a pre-eminent status, helping to anchor Maturidism durably as the dominant theology of the Indian subcontinent, where it remains associated today with the great local Hanafi schools of thought^[76].

Maturidism today

Today, Maturidism and Ash'arism are generally presented, within majority Sunnism, as the two equally orthodox theological schools of classical kalām — their divergences commonly minimised as concerning, in the words of a contemporary Muslim publisher quoted by Wikipedia, internal nuances rather than any real doctrinal opposition: "there is no major doctrinal difference between the Ash'arites and the Maturidis, which is why both groups are today called People of the Sunna"^[77]. This double recognition does not exclude renewed tensions: contemporary Salafi and Wahhabi currents, hostile in principle to any theology employing rational kalām, continue to reject both Ash'arism and Maturidism as undue theological innovations — a rejection which, as recalled in the companion article on Ibn Taymiyya, has its roots in a Hanbali controversy well before al-Māturīdī himself^[78].

A natural theology that partly meets Catholic teaching

The point most worthy of attention, for a Catholic reader, in the theology of al-Māturīdī, is precisely the one that distinguishes him most sharply from al-Ash'ari: his rationalist insistence on the knowability of God independently of any revelation received. On this precise point, the Hanafi position defended by al-Māturīdī converges, strikingly, with the constant teaching of the Catholic Church on natural theology. The First Vatican Council teaches that God, "the principle and end of all things, can be known with certainty from created things, by the natural light of human reason" — a teaching taken up by the Catechism of the Catholic Church, echoing Saint Paul's affirmation that the invisible attributes of God "can be seen by the intellect through his works, since the creation of the world," so that men are "without excuse" for not having recognised him^[79]. Al-Māturīdī, against al-Ash'ari, defended exactly this thesis: no one needs to wait for revelation for the reasoned observation of creation to make the recognition of a wise and unique Creator rationally compelling.

This convergence deserves to be saluted without excessive reserve or false minimisation: it testifies that human reason, whatever the religious tradition in which it operates, remains capable — as the Church herself teaches concerning the natural law — of authentically discerning something of the true God, even before any particular revelation received^[80]. It must not, however, lead to overestimating the overall proximity between the two theologies: the Catholic demonstration of the natural knowability of God belongs within an anthropology of grace and a theology of progressive revelation that remain entirely absent in al-Māturīdī — his concern remains, from start to finish, to ground rationally the obligation to recognise the Qur'anic oneness of God (tawḥīd), not to prepare for an Incarnation to come.

Takwīn and the absence of any Trinitarian life

The doctrine of takwīn, however refined on the strictly philosophical level, well illustrates this fundamental limit. By positing that God's creative act is an attribute really distinct from His essence, while remaining eternal and uncreated, al-Māturīdī brings Hanafi reflection on the divine attributes to a degree of precision that no other school of kalām then attained. But this distinction remains, from beginning to end, strictly functional: it never claims to introduce, within the divine being, any plurality of real, subsistent relations comparable to the Persons of the Christian Trinity. The Catechism of the Catholic Church teaches that the Father, the Son and the Holy Spirit are really distinct from one another, not by a difference of essence or functional attribute, but by subsistent relations of origin — the Father begetting the Son, the Spirit proceeding from the Father and the Son — a mystery that natural reason alone could neither discover nor even suspect^[81]. Nothing comparable, even remotely, is found in the most refined theology of classical Sunni kalām, Ash'arite or Maturidi: the monotheism they defend with such rigour remains, on this precise point, a strictly unitary monotheism, with no structural place for a Trinitarian life interior to God — nor, consequently, for the Incarnation of the Word explicitly denied by the Qur'an, a question already developed in the dossier Islam and the Catholic response.

Kasb, istiṭāʿa and the question of grace

Finally, the Maturidi doctrine of the two capacities for acting (istiṭāʿa) — a prior bodily capacity, a capacity of choice granted at the very moment of the act — poses, in a technical form proper to Islam, a question structurally analogous to the one Catholic theology treats under the name of the relationship between grace and free will^[82]. The companion article on Al-Ash'ari develops this comparison in greater detail regarding Ash'arite kasb; suffice it to note here that al-Māturīdī, by granting man a real and distinct capacity of choice, logically prior to the act, leaves more room for human moral responsibility than the Ash'arite theory of kasb — without thereby joining the Catholic doctrine of an efficacious grace that elevates and inwardly transforms human freedom rather than merely granting it, at the moment of the act, an extrinsic capacity.

• Muhammad (c. 570–632) — the life of the prophet of Islam, claimed by the whole theological tradition that al-Māturīdī systematises in his own way.
• Islam and the Catholic response — the overall doctrinal dossier on the Qur'an, Qur'anic Christology and the Catholic apologetic response.
• What the Church says about Islam — the contemporary magisterial position, from Vatican II to the Catechism.
• Abū Ḥanīfa (699–767) — the founder of the Hanafi legal school to which al-Māturīdī remains faithful all his life.
• Al-Ash'ari (874–936) — the contemporary founder of the other great theological school of classical Sunnism, with a broader comparative table of Mu'tazilite, Ash'arite, Hanbali and Maturidi positions.
• Ibn Taymiyya (1263–1328) — the Hanbali theologian whose critique of rational kalām, Ash'arite as well as Maturidi, still nourishes contemporary Salafi currents.
