It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) appointed Sayyiduna Usama bin Zaid (may Allah be pleased with him) as the commander of the army, news reached the Prophet (peace and blessings be upon him) that people were objecting to Usama (may Allah be pleased with him) being made the commander and were criticizing his appointment as leader. So the Prophet (peace and blessings be upon him) stood up and said: "You people object to Usama being appointed as the commander of the army and criticize his being made the leader. You did the same regarding his father before this, even though he was truly deserving of being made the leader. And he was the most beloved to me. After him, this son of his is among the dearest of people to me. I advise you to treat him well; he is among your best people."
