Battle of Khaybar
Imran ibn Husain and his father, Husain ibn Ubayd, both embraced Islam in the seventh year after "hijra", following the Battle of Khaybar. He participated in several battles under the leadership of Muhammad, and he held the banner of his tribe, the Banū Khuzā‘ah amid the Conquest of Mecca. During the caliphate of Umar Ibn Al-Khattab, Imran was sent to Basra, to preside as a judge and instruct its inhabitants in Islamic jurisprudence and administer as lieutenant to governor Abu Musa Ashāri while he was away from Basra. Hasan Al-Basri and Ibn Sirin said of him, "No one of Rasulullah’s Companions who entered Basra can be considered better than Imran Ibn Husain."
