Muhammad Ahmad Hussein is the head imam and manager of the al-Aqsa Mosque and was assigned the role of Grand Mufti of Jerusalem in 2006 by Palestinian president Mahmoud Abbas. Ownership of the al-Aqsa Mosque is a contentious issue in the Israel-Palestinian conflict. Israel claims sovereignty over the mosque along with all of the Temple Mount (Noble Sanctuary), but Palestinians hold the custodianship of the site through the Islamic waqf. During the negotiations at the 2000 Camp David Summit, Palestinians demanded complete ownership of the mosque and other Islamic holy sites in East Jerusalem.
