Abu Ja'far Ahmad ibn Nasr

Abu Ja'far Ahmad ibn Nasr (أبوجعفر أحمد بن نصر) was a merchant and Isma'ili dāʿī. He operated openly as the head of the pro-Fatimid propaganda in Fustat, the capital of Egypt, during the last years of Ikhshidid rule, and played a major role in preparing the quick and relatively bloodless Fatimid conquest of Egypt in 969.
