His epithet al-Abharī suggests that he or his ancestors originally stem from the Abhar tribe.[1] He is said to have been a student or teacher in various schools at Khurāsān, Baghdad, and Arbil, living for some time in Sivas.[1] Ibn Khallikān reports that he was student of Kamāl al‐Dīn ibn Yūnus, but other sources state that he worked as an assistant to Fakhr al‐Dīn al‐Rāzī. He may have died of paralysis in Azerbaijan.[1]
