Under the Umayyads the focus of Muslim ritual ceremonies and pilgrimage in Jerusalem was the Temple Mount and to a lesser extent the Prayer Niche of David (possibly the Tower of David), the Spring of Silwan, the Garden of Gethsemane and Mary's Tomb, and the Mount of Olives. The Umayyads encouraged Muslim pilgrimage and prayer in Jerusalem and traditions originated during the Umayyad period celebrated the city. During this period, Muslim pilgrims came to Jerusalem to sanctify themselves before making the Umra or Hajj pilgrimages to Mecca. Muslims who could not make the pilgrimage, and possibly Christians and Jews, donated olive oil for the illumination of the al-Aqsa Mosque. The bulk of the Muslim pilgrims to Jerusalem were presumably from Palestine and Syria in general, though several came from distant parts of the Caliphate.
