Yazid ibn al-Muhallab
The resurgence of the Azariqa in Ahwaz in 688/89 saw him transferred once again to that front by the Zubayrids. When the latter were ousted from Iraq by the Umayyads in 691, al-Muhallab switched allegiance to the Umayyad caliph Abd al-Malik (), who kept him in command of the war with the Azariqa. With the key support of the powerful Umayyad governor of Iraq, al-Hajjaj ibn Yusuf, al-Muhallab decisively defeated the Kharijites in 698. Throughout the thirteen-year conflict with the Kharijites, al-Muhallab was consistently viewed as indispensable by the Basrans and their successive Zubayrid and Umayyad rulers. Al-Hajjaj made al-Muhallab governor of Khurasan in 698. From there, he recommenced the Arab conquests in Transoxiana, leading a two-year-long siege of the fortress of Kish. He was ultimately compelled to withdraw to his capital in Merv and died on the way there. He was succeeded by his son Yazid ibn al-Muhallab.
