The Prophet (peace and blessings be upon him) also once appointed Amr ibn al-Ās as commander during the expedition of Dhāt al-Salāsil—in order to win over his relatives, to whom he was sent—placing him over men who were superior to him (1). He appointed Usāmah ibn Zayd as commander so that he might seek redress for his father’s death (2). In the same way, he would appoint a man when an overriding interest called for it, even though some of those under his command might surpass him in knowledge and faith.

Thus, for each of them, the soundest course was to appoint the man he did [أ/ق 7], so that his administration would be balanced and he would thereby be one of the successors of Allah’s Messenger (peace and blessings be upon him), whose own disposition was balanced. The Messenger of Allah (peace and blessings be upon him) even said, “I am the Prophet of mercy; I am the Prophet of
