The Banū Qushayr (Arabic: بنو قشير) was a branch of the Arab tribe of Banu Amir, historically resident in central Arabian Peninsula and later spreading to Khurasan, Iraq, Upper Mesopotamia.
[1] The mother of Qushayr was Rayta bint Kunfudh ibn Malik of the Banu Sulaym.
[1] In the pre-Islamic period, the Qushayr were attached to their parent tribe, the Banu Amir, and were resided in the region of al-Yamama (central Arabia).
During the Muslim conquests of Syria and Mesopotamia, the Qushayr participated, but did not play a distinguished role.
During the Umayyad period (661–750), they maintained great numbers and power in that province and many of its governors, including Zurara ibn Uqba, hailed from the Salama al-Khayr family.
