Sheikh Abdelqader Al-Muzaffar, barely visible in the centre-right of the photograph, is addressing a rally of Yemeni and Wahhabi (i.e. Najdi) pilgrims in Mecca in 1920 in his capacity as leader of the Palestinian “Haj” (pilgrimage) delegation about the situation in Palestine and what the Zionists plan on doing with the Islamic holy sites in Jerusalem. Al-Muzaffar invited the crowd to add its voice to that of the other Arabs in defence of the Al-Aqsa mosque in Jerusalem.
