A physician who studied under and worked with in Baghdad. Ibrahim was, after coming to Egypt, a personal physician to the amir ibn Tulun (868-884), whom he used to accompany on his journeys. He remained in the amir’s service and continued to reside in al-Fustat (Old Cairo) until his death, around 874. He may be the same Ibrahim ibn ‘Isa mentioned by Ibn al-Nadim as author of two works, Akhbar al-Khawarij ( of the Kharijites) and Kitab al-Rasa’il (Book of Epistles). Ibn Abi Usaybi‘ah, who gives this brief account of his life, does not mention to which Christian community he belonged.
