[1] After receiving his appointment, he established himself in Basra; he also ordered the arrest of his predecessor Yazid ibn al-Muhallab, whom Umar had dismissed from the governorship of Iraq.
[3] Oman was also initially under Adi's authority, but Umar revoked his jurisdiction over it after receiving complaints about his lieutenant's administration there.
[5] During Adi's governorship, he authorized public works projects in Basra; a canal was dug to provide water to the city's residents and was named after him.
On the caliph's orders, Adi arrested and imprisoned the Muhallabids who were in Basra and prepared for a confrontation with Yazid; the local army was organized and a trench was dug around the city.
When news of Yazid's fate reached Wasit, Mu'awiya took out a number of prisoners under his charge, including Adi and his son Muhammad, and executed them in retaliation for his father's death.
