Qadi al-Nu'man

Abu Hanifa al-Nu‘man ibn Muhammad ibn Mansur ibn Ahmad ibn Hayyun al-Tamimi, generally known as al-Qāḍī al-Nu‘mān also Qāżi Noʿmān (died 974 CE/ 363 AH) was an Isma'ili jurist and the official historian of the Fatimid caliphs. He was also called Qadi Quddat and Da'i Duat.

Born in Qayrawan,North Africa, he converted to Isma'ili Islam and began his career in Ifriqiya (modern-day Tunisia, western Libya and eastern Algeria) under the first caliph, al-Mahdi Billah (r. 909-934 CE/ 297-322 AH), quickly rising to become the most prominent judge (qadi) of the Fatimid state. During his lifetime, he served four Fatimid Caliphs:

In his fifty years of service to the Fatimids, he wrote a vast number of books under the encouragement of the caliphs on history, biography, jurisprudence (fiqh) and the interpretation of scripture (ta'wil). After the Fatimid conquest of Egypt and Syria, al-Nu'man left Ifriqiya and travelled to the newly founded city of al-Qahira (Cairo) where he died in 974 CE/ 363 AH.

He has written 44 books on Fiqh, history, religious beliefs and Ta’wil.

Al-Nu'man's most prominent work, the Daim al-Islam (Arabic:دعائم الاسلام)('The Pillars of Islam'), which took nearly thirty years to complete, is an exposition of the Fatimid jurisprudence. The work that was finally completed during the reign of the fourth caliph, al-Mu'izz li-din Allah (r. 953-975 CE/ 341-365 AH), was accepted in its time as the official code of the Fatimid state, and serves to this day as the primary source of law (sharia) for some Mustaali Isma'ili communities, especially the Tayyibis. Iran has incorporated Daim-ul-Islam into their constitution.
