Tafsir al-Razi = Mafatih al-Ghayb aw al-Tafsir al-Kabir

Mafatih al-Ghayb (Keys to the Unseen), also known as al-Tafsir al-Kabir (The Grand Commentary), is an extensive Quranic exegesis by the Shafi'i theologian and polymath Fakhr al-Din al-Razi (544–606 AH / 1150–1210 CE; also reported 543 AH) Kashf al-Zunun an Asami a…+1. It is considered one of the most comprehensive and prominent works of rational Quranic exegesis (tafsir bi-l-ra'y), integrating linguistic, theological, legal, and natural scientific inquiries Madkhal ila al-Tafsir wa …+1.

Composition and Completion

In the opening of the commentary, al-Razi relates that he had remarked that ten thousand benefits and points of knowledge could be derived from Surah al-Fatihah alone; when critics expressed doubt, he began composing the work with an extensive introduction and dedicated an entire volume to al-Fatihah Kashf al-Zunun an Asami a…+1.

Biographers and bibliographers disagree as to whether al-Razi completed the commentary himself or died before its conclusion Madkhal ila al-Tafsir wa …+1. Scholars such as Ibn Khallikan and Ibn Qadi Shuhbah stated that he left it incomplete, with some accounts noting that his writing reached Surah al-Anbiya Fi Ulum al-Quran Dirasat …+1. Supplements (takmilah) were composed to complete the missing portions: one by Chief Judge Shihab al-Din Ahmad ibn Khalil al-Khuwayyi (d. 639 AH / 1241 CE) and another by Najm al-Din Ahmad ibn Muhammad al-Qamuli (d. 727 AH / 1327 CE; also reported 828 AH) Madkhal ila al-Tafsir wa …+1. Later scholars observed that the supplements adhere closely to al-Razi's style and structural method, making it difficult for readers to distinguish between the original text and its completions Lamahat fi al-Maktaba wa …+1.

Method and Content

Al-Razi's method in Mafatih al-Ghayb is characterized by several distinctive features:

• Textual correlations (munasabat): The commentary places exceptional emphasis on the thematic and textual links between adjacent verses and consecutive surahs, frequently connecting the opening and concluding passages of a given chapter Madkhal ila al-Tafsir wa …+1.
• Theological and philosophical discourse: Drawing on dialectical theology (kalam), al-Razi champions Sunni Ash'ari doctrines, refuting opposing views—particularly those of the Mu'tazilites and philosophers—by systematically presenting their arguments and dismantling them using rational proofs al-Israiliyat wal-Mawduat…+1.
• Natural sciences and cosmology: When addressing verses that touch on the physical world and celestial bodies, al-Razi incorporates detailed discussions on astronomy (ilm al-hay'ah), physics, geometry, and medicine Dirasat fi Ulum al-Quran …+1.
• Jurisprudence and legal theory: In passages addressing legal rulings (ayat al-ahkam), he details the positions of various legal schools, defending Shafi'i jurisprudence through the principles of legal theory (usul al-fiqh) Lamahat fi al-Maktaba wa …+1.
• Treatment of Isra'iliyyat: The work contains relatively few Judeo-Christian biblical traditions (Isra'iliyyat); where al-Razi cites them, it is primarily to scrutinize and reject them, as in his discussions of the stories of Harut and Marut, David, Solomon, and the narration of the Gharaniq al-Israiliyat wal-Mawduat….

Reception and Critique

Ibn Khallikan praised Mafatih al-Ghayb, remarking that al-Razi "gathered in it every rare and remarkable point" Madkhal ila al-Tafsir wa …+1. However, its extensive digressions into dialectical theology and natural sciences prompted some scholars, such as Abu Hayyan al-Gharnati, to critically remark that "it contains everything except exegesis" Mabahith fi Ulum al-Quran…+1. Other scholars responded to this critique by maintaining that, despite its scientific and theological excursions, the work thoroughly addresses the core linguistic and contextual requirements of Quranic exegesis Durus al-Shaykh Aidh al-Q…+1.

Another critique reported by biographers such as Ibn Hajar al-Asqalani was that al-Razi presented the counterarguments and doubts of theological opponents in exhaustive, formidable detail, while at times offering comparatively brief or weaker solutions to them Dirasat fi Ulum al-Quran …+1.

Abridgments and Editions

Due to its vast length, the commentary was abridged and adapted by subsequent scholars:

• Burhan al-Din Muhammad ibn Muhammad al-Nasafi (d. 687 AH / 1288 CE; also reported 686 AH) abridged it under the title al-Wadih Kashf al-Zunun an Asami a….
• Muhammad ibn al-Qadi Bayathlugh produced an abridgment incorporating additional notes Kashf al-Zunun an Asami a….
• Nizam al-Din al-Nisaburi drew heavily upon al-Razi's commentary, condensing its theological and scientific discussions alongside al-Zamakhshari's al-Kashshaf in his own work, Ghara'ib al-Qur'an wa-Ragha'ib al-Furqan Tafsir al-Naysaburi = Gha….

The full work has been printed in multiple editions, historically spanning eight large volumes and published in thirty-two parts in modern printings, including an edition edited by Muhammad Muhyi al-Din Abd al-Hamid in 1352 AH Fi Ulum al-Quran Dirasat …+1.
