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.
[2] Reports in the early Islamic tradition mentioned a particular incident that aroused Ansarite hostility, namely that al-Harith used his post to purchase goods and sell them in the market at considerable profit.
Protests lodged to the caliph in response were dismissed and the Ansar became further angered when Uthman awarded al-Harith a gift of camels collected as sadaqa (alms tax).
[4] Uthman had previously angered members of the community, particularly Abu Dharr al-Ghifari, when he awarded al-Harith a huge sum of money from the tribute collected during the military campaigns in Byzantine North Africa.
[8] Al-Harith's grandson, Sa'id ibn Abd al-Aziz, commonly and derogatorily known as Sa'id Khudhayna (khudhayna was a term used by the Arabs to refer to the wives of Iranian nobles and essentially meant 'little princess') was the governor Khurasan in 720 under his father-in-law Maslama ibn Abd al-Malik, a grandson of Marwan I.
