Al-Hakim bi-Amr Allah, sixth FatimidCaliph of Egypt disappears on a trip to al-Muqattam hills. He is presumed deceased and succeeded by Ali az-Zahir . However the Druzes, a sect of IsmailiMuslims, believe him to have been hidden away by God (Allah) and begin worshiping him in the mountains of Lebanon. He is the first Caliph to be worshipped as being Divine in his own right.
