Humayd ibn Hurayth ibn Bahdal
Humayd ibn Hurayth ibn Bahdal al-Kalbi (; ) was a senior Umayyad commander and a chieftain of the Banu Kalb tribe. He was head of the shurṭa (security forces) under caliphs Marwan I and Abd al-Malik, and may have served in the same capacity under their predecessor Caliph Yazid I. He commanded the Kalbi-dominated shurṭa in the Battle of Khazir in 686, and a year later joined the rebellion of the Umayyad prince Amr ibn Sa'id ibn al-As against Abd al-Malik. After the revolt's failure, Humayd reconciled with the latter. In the years following the battles of Marj Rahit (684) and Khazir, Humayd led the Kalb in numerous tit-for-tat raids and battles with enemy Qaysi tribes, including the Banu Amir, Banu Sulaym and Fazara. Family Humayd ibn Hurayth was a grandson of Bahdal ibn Unayf, the preeminent chieftain of the Banu Kalb tribe. Humayd's family and tribe had kinship ties with the early Umayyad caliphs Mu'awiya I (), Yazid I () and Mu'awiya II () and gained influential positions in the Umayyad state. Humayd's cousins Hassan ibn Malik and Sa'id ibn Malik served as the governors of various Syrian ajnad (military districts) during the reigns of the aforementioned caliphs. Career
