Jammaz ibn Hasan

Jammāz ibn al-Ḥasan ibn Qatādah ibn Idrīs al-Ḥasanī was Emir of Mecca for a few months from 1253 to 1254.

Emir of Mecca Jammaz sought the assistance of an-Nasir Yusuf, the Ayyubid Sultan of Damascus, against his cousin Abu Sa'd al-Hasan, the Emir of Mecca. Supported by Syrian troops Jammaz entered Mecca in Ramadan 651 AH (October/November 1253) and deposed and killed Abu Sa'd. However, he reneged on his promise to put al-Nasir's name in the khutbah, and instead continued the khutbah in the name of the Sultan of Yemen, al-Muzaffar Yusuf.

On the last day of Dhu al-Hijjah his uncle Rajih ibn Qatadah took the Emirate from him without resistance, and Jammaz fled to Yanbu.

Descendants The later Emirs of Yanbu were from among his progeny.
