Ibn Jumay‘ was born to a Jewish family in Fustat, Egypt. He studied with the physician Ibn al-‘Aynzarbī (died 1153/AH 548) and entered the service of Saladin. According to Ibn Abi Usaibia's Lives of the Physicians, Ibn Jumay‘ wrote eight works on medical-related subjects.
A contemporary of Moses Maimonides, Ibn Jumay‘ "became famous for having prevented a person having a cataleptic fit from being buried alive. He was the author of a number of medical writings, including al-Irshād li-maṣāliḥ, dedicated to al-Baysanī, the vizier to Saladin, and completed by Ibn Jumay‘ al-Isrā’īlī's son Abū Tahir Ismā‘īl."
