Abū al-Futūḥ Rāzī, Ḥusayn ibn ʻAlī, active 1087-1131

Abu al-Futuh al-Razi (Arabic: أبو الفتوح الرازي), full name Abū al-Futūḥ al-Ḥusayn ibn ʿAlī ibn Muḥammad ibn Aḥmad al-Khuzāʿī al-Rāzī al-Nīsābūrī (أبو الفتوح الحسين بن علي بن محمد بن أحمد الخزاعي الرازي النيسابوري) or Abu al-Futuh Jamal al-Din al-Razi al-Nisaburi (أبو الفتوح جمال ادين الرازي النيسابوري), also known as Khaza'i Nishaburi (fl. 6th A.H./12th century), was a Shiʿite theologian and author. He came from an Arab family originally from Nishapur and supposedly from the Khuza'a tribe, which settled in Nishapur. His grandfather had moved to Rayy, where he taught and later died in or after 1131 CE. His most famous work, Rawz al-jinan wa Ruh al-Janan, is considered the first Persian-language exegesis on the Quran. The book, consisting of twenty volumes, is the earliest surviving Persian tafsīr with an Imāmī Shīʿī emphasis. It delves into mystical themes regularly.
