Note 70 — Chapter III · THE SPREAD OF ISLAM AMONG THE CHRISTIAN NATIONS OF WESTERN ASIA.

In the reign of al-Muʻtadid (892–902), the governor of Anbār, ʻUmar b. Yūsuf, was a Christian, and the caliph approved of the appointment on the ground that if a Christian were found to be competent, a post might well be given to him, as there were better reasons for trusting a Christian than either a Jew, a Muslim or a Zoroastrian.70 Al-Muwaffaq, who was virtual ruler of the empire during the reign of his brother al-Muʻtamid (870–892), entrusted the administration of the army to a Christian named Israel, and his son, al-Muʻtaḍid, had as one of his secretaries another Christian, Malik b. al-Walīd. In a later reign, that of al-Muqtadir (908–932), a Christian was again in charge of the war office.71
