الحاكم بأمر الله
The Mosque of al-Hakim (), nicknamed al-Anwar (), is a major Islamic religious site in Cairo, Egypt. It is named after Al-Hakim bi-Amr Allah (985–1021), the sixth Fatimid caliph and 16th Ismaili Imam. This mosque originally started being built by al-Aziz, the son of Mu'izz, and the father of al Hakim, in 990 A.D. It was named after Al Hakim because he had finished and established it.
