Hamid al-Din al-Kirmani

Hamid al-Din Abu'l-Hasan Ahmad ibn Abdallah al-Kirmani (Arabic: حميد الدين الكرماني; fl. 996–1021 CE) was an Isma'ili scholar. He was of Persian origin and was probably born in the province of Kirman. He seems to have spent the greater part of his life as a Fatimid da'i (missionary) in Baghdad and Basra. He was a theologian and philosopher who rose to prominence during the Fatimid caliph-imam al-Hakim bi Amr Allah.

A prominent Ismaili da'i or missionary, he was considered by the central headquarters of the Fatimid da'wa in Cairo as one of the most learned Ismaili theologians and philosophers of the Fatimid period. It was in that capacity that al-Kirmani played an important role in refuting the extremist ideas of some of the dissident da'is, who by proclaiming al-Hakim's divinity had initiated the Druze movement. Al-Kirmani was summoned in 1014 or shortly earlier to Cairo where he produced several works to disclaim these extremist doctrines. Al-Kirmani's writings, which were widely circulated, were to some extent successful in checking the spread of the extremist doctrines.
