Al-Harith ibn al-Hakam

Al-Ḥārith ibn al-Ḥakam ibn Abī al-ʿĀṣ ibn Umayya was a senior adviser and cousin of Caliph Uthman (r. 644–656). He played a role in the expedition against the Byzantines of North Africa in 647 and was later appointed supervisor of the market in the caliphal capital of Medina. A number of his descendants were active as estate holders and governors under their paternal kinsmen, the Umayyad caliphs, particularly the Marwanid house of al-Harith's brother Marwan I which ruled from 684 until 750.
