Seerah al-Razi al-Kabir — Fakhr al-Din al-Razi (1149-1209 CE): The Philosopher-Theologian Whose 32-Volume Mafatih al-Ghayb (Tafsir al-Kabir) Is the Greatest Work of Kalam-Philosophical Quran Commentary, Who Was Called the 'Imam of Doubters' for His Rigorous Articulation of Theological Objections, and Who Synthesized Peripatetic Philosophy with Ash'ari Kalam

Seerah al-Razi al-Kabir (سِيرَةُ الرَّازِيِّ الكَبِير; full name: Muhammad ibn 'Umar Fakhr al-Din al-Razi; born 544 AH / 1149 CE in Ray [near modern Tehran]; died 606 AH / 1209 CE in Herat [modern Afghanistan]; a Shafi'i jurist and Ash'ari theologian who was simultaneously one of the most significant Islamic philosophers; the range of his scholarship: al-Razi wrote on kalam [theology], philosophy [including commentary on Ibn Sina], tafsir, fiqh, medicine, mathematics, and natural philosophy; he engaged every major intellectual tradition of his era; the major tafsir: Mafatih al-Ghayb [The Keys to the Unseen], universally called al-Tafsir al-Kabir [The Great Commentary]: 32 volumes in standard editions; the most comprehensive kalam-philosophical tafsir in Islamic history; al-Razi's method: for each verse, he [1] presents the linguistic/grammatical analysis [following al-Zamakhshari's approach]; [2] explores the full range of interpretive questions the verse raises; [3] articulates theological questions and objections [often very rigorously]; [4] engages philosophical questions raised by the verse's content; [5] defends the Ash'ari theological position; the result is a tafsir that functions simultaneously as a work of tafsir, kalam, and Islamic philosophy; the 'Imam of Doubters' epithet: al-Razi earned this reputation for the vigor and precision with which he articulated theological objections before refuting them; critics argued that he articulated the objections better than his refutations; the famous saying attributed to him: 'The objections are lions; the answers are mice'; he himself reportedly said in his final days that he remained uncertain about some of the questions he had spent his life discussing; this intellectual honesty about doubt within faith is rare and significant; major other works: [1] al-Arba'in fi Usul al-Din [The Forty on the Foundations of Religion]: a kalam text; [2] al-Mahsul fi 'Ilm al-Usul [The Product of the Knowledge of Jurisprudential Principles]: a major usul al-fiqh text; [3] al-Matalib al-'Aliya [The High Aims]: a work of Islamic metaphysics and natural philosophy; [4] Sharh al-Isharat [Commentary on Ibn Sina's al-Isharat wal-Tanbihat]: al-Razi's critical engagement with Ibn Sina's philosophical system; his relationship with Sufism: al-Razi's later career showed increasing interest in Sufism; his final works have a more mystical tone; his last days in Herat reportedly included significant engagement with Sufi teachings; the biography is unclear on how much his earlier confident philosophical theology was superseded; his death: al-Razi died in Herat in 1209 CE, reportedly after eating a poisoned melon — the death may have been natural but was attributed by some to enemies [the Karramiyya sect had opposed him vigorously]; the context: he lived through the final decades before the Mongol invasions would transform the Islamic world; the library tradition he represents was shattered by those events; legacy: al-Tafsir al-Kabir is still read for its philosophical-theological analysis; no subsequent work has replaced it for the depth of its kalam engagement with the Quranic text) is the Islamic intellectual tradition's greatest rationalist Quran commentator.
