Амр ибн аль-Ас
As 'Amr's tent was to be the focal point of the city, the city was called Fustat, meaning in Arabic "the tent". The first structure to be built was the mosque that later became famous as Mosque of 'Amr ibn al-'As. In the course of time, Fustat extended to include the old town of Babylon to the west, becoming the bustling commercial centre of Egypt.
