The opening as it read in 2025

Jami al-Qarafa Mosque or Qarafa Mosque , was the second major mosque built by the Fatimid dynasty in their new capital of Cairo after their conquest of Egypt in 969. It was located in the Qarafa , the great necropolis of Cairo and Fustat . The mosque was built in 976 by order of Al-Sayyida al-Mu'iziyya (also known as Durzan) , mother of the Caliph al-'Aziz (r. 975–996), and her daughter Sitt al-Malik. It occupied the site of the older mosque of the Dome ( Masjid al-Qubba ), and apparently was very large. The historian al-Maqrizi says it was one of the most beautiful buildings of its day. A possible layout was described by Jonathan Bloom in his "The Mosque of the Qarafa", although Yūsuf Rāghib pointed out problems with this reconstruction in his "La mosquée d'al-Qarāfa." In Bloom's opinion, the mosque had a central aisle, wider than the others and with a higher roof, that led a dome over the spaces before the mihrab . This was similar to the mosques of al-Azhar and al-Hākim bi-Amr Allāh. The courtyard provided a place where the elite of Cairo would meet on Friday evenings in summer, and the covered qibla part of the mosque gave them a meeting place in the cooler weather. State festivals would be held at the mosque in which food was distributed to all classes of people. According to Ibn al-Zayyāt, it was an especially holy mosque, one where people would seek refuge in times of trouble. When a great fire burned down most of al-Fustat in 1168 the mosque was almost completed destroyed, with only its green mihrab being preserved. It was later rebuilt as the Jami' al-Awliyya, but was little used after al-Qarafa became depopulated following a crisis in 1403.
