Others among his wide circle of elites were Ali ibn Harun ibn al-Munajjim (d. 963), of the Banu Munajjim and the Christian philosopher Ibn al-Khammar. He admired Abu Sulayman Sijistani, son of Ali bin Isa the "Good Vizier" of the Banu al-Jarrah, for his knowledge of philosophy, logic and the Greek, Persian and Indian sciences, especially Aristotle. The physician Ibn Abi Usaibia (d. 1273), mentions al-Nadim thirteen times and calls him a writer, or perhaps a government secretary. Al-Nadim's "kunya" 'Abu al-Faraj' indicates he was married with at least one son.
