F. F. Arbuthnot, Arabic Authors
“ In A.D. 909, the Fatimites, so designated from one Obaid Allah, a real or pretended descendant of Ali and Fatima, the daughter of Muhammad, established themselves in the North of Africa, and consolidated their power there. In A.D. 972 Al-Moizz, or Abu Tamim, a great-grandson of Obaid Allah, the founder of the Fatimite dynasty at Tunis, sent his general Jawhar with an army to invade Egypt. The country was conquered, the city of Cairo built, the seat of government was transferred there, and the title of Khalif assumed by the Fatimites. ”
