Zufar ibn al-Harith al-Kilabi

Abu al-Hudhayl Zufar ibn al-Harith al-Kilabi was a Muslim commander, a chieftain of the Arabian tribe of Banu Amir, and the preeminent leader of the Qays tribal–political faction in the late 7th century. During the First Muslim Civil War he commanded his tribe in A'isha's army against Caliph Ali's forces at the Battle of the Camel near Basra in 656. The following year, he relocated from Iraq to the Jazira and fought under Mu'awiya ibn Abi Sufyan, future founder of the Umayyad Caliphate, against Ali at the Battle of Siffin. During the Second Muslim Civil War he served Mu'awiya's son, Caliph Yazid I, leading the troops of Jund Qinnasrin against anti-Umayyad rebels in the 683 Battle of al-Harra.
