Among those who transmitted from him were Ibn al-ʿAdīm and his page, Baybars the Turk. By formal authorization, Fakhr Ibn ʿAsākir and a number of others also received from him. Ibn al-Najjār likewise narrated on his authority and said that he died in Jumada al-Ula (1), in the year 645 AH (2).
I add: his son also died:
150 – al-Ṣadr Tāj al-Dīn ʿAlī al-Ḥājib
He passed away in 656 AH, when he was in his seventies. He narrated from Ibn Kulayb, and al-Dimyāṭī studied under him. He was the brother of Muḥammad ibn Hibatu Allah.
151 – al-Hadhbānī, Yaʿqūb ibn Muḥammad ibn al-Ḥasan ibn ʿĪsā al-Kurdi*
The eminent commander, learned imam, and scholar Sharaf al-Dīn Yaʿqūb ibn Muḥammad ibn al-Ḥasan ibn ʿĪsā al-Kurdi, originally from Mosul, was counted among the leading emirs of Egypt.
(1) According to Tarikh al-Islam, he died on 26 Jumada al-Ula 645/1247. Most chroniclers give the same year, except the author of Al-Hawadith al-Jami‘a, who places his death in 646/1248.
(2) This is a serious oversight on the part of Imam al-Dhahabi: how could he cite Ibn al-Najjar as dying in 645 when Ibn al-Najjar himself died in 643/1245? Most likely the date was added to a copy of Ibn al-Najjar’s Tarikh after his death, and al-Dhahabi, when quoting, did not notice the interpolation. Similar cases occur frequently in Ibn Saad’s Tabaqat and other works.
