The khutba changes at the Mosque of Amr
On the Friday conventionally dated 9 July 969, the sermon in the old Mosque of Amr at Fustat was delivered for the Fatimid imam-caliph al-Mu'izz rather than for the Abbasid caliph, publicly marking the new allegiance of Egypt's principal mosque. Conversion of the Islamic date produces 8 July in some modern scholarship; the underlying source describes it as a Friday with ten days remaining in Sha'ban.
Jawhar, the commander who had taken the city for al-Mu'izz, attended with his army. The preacher appeared in Fatimid white in place of Abbasid black.
The sermon added explicitly Shi'i invocations for Muhammad, Ali, Fatima, Hasan, Husayn and the Fatimid imam-caliph's ancestors.
The written guarantee that came first
The ceremony followed a negotiated guarantee of safety for Fustat, and limited fighting against Ikhshidid and Kafurid soldiers who had rejected the agreement.
A delegation of five negotiated that guarantee on behalf of the city's notables. Abu Ja'far Muslim al-Husayni led it and later helped renew it; Ja'far ibn al-Furat, the Ikhshidid vizier, represented the surviving Egyptian administration during the transition.
Jawhar's written guarantee protected life and property and allowed the Sunni legal schools to continue.
A royal enclosure goes up beside the city
By this point Jawhar's forces controlled Fustat and Ikhshidid government there had ended. He immediately began accommodating the existing communities while constructing a new royal enclosure to the north — about two miles from Fustat, as the Cambridge History of Egypt summarizes it.
That enclosure was the beginning of the city now called Cairo. Fustat was not built over; it continued as a major populated and commercial city beside the new Fatimid royal centre.
Jawhar governed Egypt in the caliph's absence.

Date disputed. Sources disagree; the research places it at 0969-07-09.
What the sources leave uncertain
- The slug's 6 February date marks the army's departure from Ifriqiya, not the Fustat event described by the title. Some modern conversions render that departure as 5 rather than 6 February.
- The first Fatimid sermon is conventionally dated 9 July, but conversion of the Islamic date produces 8 July in some modern scholarship. The underlying source describes it as Friday with ten days remaining in Sha'ban.
- The takeover was relatively bloodless compared with many conquests, but it was not entirely peaceful: military factions rejected the first guarantee and fought Jawhar's forces.
- Cairo was begun immediately after the conquest as a royal enclosure; it did not instantly replace populous Fustat in every urban or administrative function.
