(1) Al-Dhahabi does not give the date of death here, although he does mention it in both his Ta rikh al-Islam and al-Ibar. ʿIzz al-Din al-Husayni, al-Yunini and Ibn Shakir al-Kutbi all specify that he died on the first day of Dhu al-Qaʿda, 655/1257. (*) Principal sources: – Al-Hawadith al-jamia, p. 310 – Al-Dhahabi, Ta rikh al-Islam (Aya Sofya MS 3013), vol. 20, fol. 142 – Al-Safadi, Al-Wafi bi-l-wafayat, 2/253, no. 818 – Al-Isnawi, Tabaqat al-Shafiʿiyya, 1/451, no. 407 – Umar Rida Kahhala, Muʿjam al-mu allifin, 9/244 (with references to notices that do not pertain to him). (2) Al-Wafi gives his father’s name as Muhammad b. al-Hasan; another report has it as Muhammad b. al-Husayn. (3) The added information comes from the book’s introduction, quoted by Haji Khalifa in Kashf al-zunun, 2/1615. The marginal note on the word al-mahsul in the main text corrects it to al-hasil. In Ta rikh al-Islam the work is likewise called al-mahsul, although the well-known al-Mahsul belongs to his teacher Fakhr al-Din al-Razi, author of the Qur an commentary Mafatih al-ghayb. Al-Wafi calls it al-tahsil, while al-Isnawi says he abridged al-Mahsul and entitled the epitome al-hasil. A manuscript copy is kept in the Egyptian National Library under no. 61, as recorded in its catalogue, 1/385. (4) Al-Wafi states that he died a little over eighty years old in 653/1255, while another opinion puts his death in 655/1257. Citing al-Hafiz al-Dimyati in his Muʿjam, al-Isnawi says he died before the Mongol onslaught, which occurred in Muharram 656/1258, and adds that, to the best of his recollection, the death actually took place in 653/1255.
