The Musjid serves as the focal point of any Muslim community and is the most important structure to Muslims.
Musjid of Amr ibn al-As radhiallahu anhu, Cairo, Egypt. Originally built in 642 CE, as the centre of the newly-founded capital of Egypt: Fustat. It was the first Musjid in Africa. The location for the Musjid was the site of the tent of the commander of the conquering army, Amr ibn al-As radhiallahu anhu. One corner of the Musjid contains the tomb of his son, Abdullah. Due to reconstruction over the centuries, nothing of the original remains, but the rebuilt Musjid is a prominent landmark in Cairo. The original layout was a simple rectangle 29m x 17m. It had columns made from palm tree trunks, stones and mud bricks, covered by a roof of wood and palm leaves. The floor was gravel. It was rebuilt in 673 by Muawiya radhiallahu anhu, who added 4 minarets.
