Zufar ibn al-Ḥārith al-Kilābī (also known as Zufar Abū al-Hudhayl)[note 1] was a Muslim general, chieftain of the Arab tribe of Banu 'Amir, and the preeminent leader of the Qays faction in the 7th century. He commanded his tribesmen in Aisha's army during the First Muslim Civil War, and later served as the Umayyad governor of Jund Qinnasrin. In 684, during the Second Fitna, he supported Abdullah ibn al-Zubayr's bid to wrest the caliphate from the Umayyads.
