‘Izz al-Dīn Ḥumayḍah ibn Muḥammad Abī Numayy al-Ḥasanī (Arabic: عز الدين حميضة بن محمد أبي نمي الحسني) was Emir of Mecca four times.
Consequently, in Dhu al-Hijjah 701 AH (August 1302), after the completion of the hajj rites, Baybars arrested Humaydah and Rumaythah, and installed their brothers to the throne.
[4] In 704 AH the shaykh Nasr al-Manbiji interceded for Humaydah and Rumaythah to forego Mamluk attire in favor of their own Hejazi dress.
[6] Finally, in Shawwal 713 AH (January/February 1314) al-Nasir dispatched an army to install Abu al-Ghayth to the throne, with 320 Mamluk cavalry and 500 horsemen from the Banu Husayn of Medina.
[7] After the Egyptian army departed Mecca, Humaydah gathered his forces and captured the city, inflicting a loss on Abu al-Ghayth of around 15 foot soldiers and over 20 horsemen.
On Tuesday, 4 Dhu al-Hijjah 714 AH (11 March 1315), Humaydah faced and defeated Abu al-Ghayth's larger force near Mecca.
Six days before the army's arrival, Humaydah loaded up a hundred camels with money and goods, burned what was left in the castle at Wadi Marr, and destroyed two thousand date palms.
Uljaytu provided Humaydah an army of several thousand Mongols and Arabs under the command of Sayyid Talib al-Dilqandi to bring the Hejaz under Ilkhanid control.
Uljaytu, who was a convert to Twelver Shi'ism, also planned to exhume the bodies of the caliphs Abu Bakr and Umar from their graves in Medina.
[10] Humaydah survived the rout, and in early 717 AH he made camp near Mecca accompanied by two Ilkhanid notables – al-Dilqandi and Malikshah – and only twenty-three men.
