Al-Mu'ayyad fi l-Din al-Shirazi (1000–1078 CE) was an 11th-century Isma'ilism scholar, philosopher-poet, preacher and theologian of Persian origin. He served the Fatimid Caliph-Imām al-Mustansir Billah as a Da'i in varying capacities, eventually attaining the highest rank of Bab al-Abwab "The Gate of Gates" and Da‘i al-Du‘at "Chief Missionary" in the Fatimid Da‘wah. In his theological and philosophical writings he brought the Isma'ili spiritual heritage to its pinnacle.[1]


Hibatullah ibn Musa was born in the town of Shiraz, capital of the Fars Province (then Persia, now in modern day Iran), in the year 1000 CE. His father, Musa ibn Dawud, served under the Fatimid Caliph-Imam al-Hakim bi Amr Allah as the Chief Missionary of the province of Fars, where the Isma'ili mission was active.

During the reign of the Fatimid Caliph-Imam Ali az-Zahir, Hibatullah ibn Musa was permitted to take over the da'wah office from his father. His title, Al-Mu'ayyad fi d-Din "The one aided in religion", was probably accorded to him around this time.

Hibatullah gradually worked his way up the hierarchy of the da‘wa and was eventually appointed Chief Missionary under the Caliph-Imam al-Mustansir Billah. In this position, he worked at the Dar al-'Ilm "House of Knowledge" teaching missionaries from both inside and outside the Fatimid Empire and composing his theological works until the end of his life in 1078 CE.

The primary source for details of al-Mu'ayyad's life are his own memoirs, the Sirat al-Mu'ayyad fi d-Din, which was written in three stages between the years 1051 and 1063 CE. He is also mentioned in the works of Nasir Khusraw, another prominent Isma'ili scholar of the time, who had learned under al-Mu'ayyad.
