al-Hakim bi-Amr Allah Ahmad al-Qabi

Second Cairo caliph [661–701], of al-Mustarshid's line — he escaped the sack to the Arabs, fought the Tatars at Ana, Haditha, Hit and Anbar, reigned first at Aleppo where Abd al-Halim ibn Taymiyya swore him, then ruled Cairo forty years, first Abbasid buried by Sayyida Nafisa. At his Cairo bay'a on 8 Muharram 661 Baybars extended his hand and swore first, then the notables, and al-Hakim invested Baybars with the sultanate; next day's khutba opened 'Praise God who raised for the Abbasid house a pillar and a backer' — and the caliph was sequestered at the Citadel of the Mountain in 663.
