Yazid ibn al-Muhallab
Adi was appointed to the governorship of Basra by the caliph Umar II, shortly after the latter's ascension in 717. After receiving his appointment, he established himself in Basra; he also ordered the arrest of his predecessor Yazid ibn al-Muhallab, who Umar had dismissed from the governorship of Iraq. Once Yazid was captured, Adi shipped him to the caliph's residence in Syria, where he was cast into prison.
