Al-Aqsa Mosque is an Islamic holy place in the Old City of Jerusalem. The mosque itself forms part of the al-Haram ash-Sharif or "Sacred Noble Sanctuary", a site also known as the Temple Mount and considered the holiest site in Judaism, since it is believed to be where the Temple in Jerusalem once stood. Widely considered, mainly by Sunni Muslims, as the third holiest site in Islam, Muslims believe that prophet Muhammad was transported from the Sacred Mosque in Mecca to al-Aqsa during the Night Journey. Islamic tradition holds that Muhammad led prayers towards this site until the seventeenth month after the emigration, when he turned towards the Ka'aba. The al-Aqsa Mosque was originally a small prayer house built by the Rashidun caliph Umar, but was rebuilt and expanded by the Ummayad caliph Abd al-Malik and finished by his son al-Walid in 705 CE. After an earthquake in 746, the mosque was completely destroyed and rebuilt by the Abbasid caliph al-Mansur in 754, and again rebuilt by his successor al-Mahdi in 780. Another earthquake destroyed most of al-Aqsa in 1033, but two years later the Fatimid caliph Ali az-Zahir built another mosque which has stood to the present-day. When the Crusaders captured Jerusalem in 1099, they used the mosque as a palace and church, but its function as a mosque was restored after its recapture by Saladin. Today, the Old City is under Israeli sovereignty, but the mosque remains under the administration of the Palestinian-led Islamic waqf.
