Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Prophet Muhammad (peace be upon him) dispatched an expedition and appointed Sayyiduna Usama bin Zaid (may Allah be pleased with them both) as their commander. Some people expressed doubt regarding his leadership, so the Prophet (peace be upon him) stood up and said: If you are expressing doubt about his leadership, then before this you also expressed doubt regarding his father. By Allah, he was worthy of leadership and was the most beloved to me, and after him, this one is the most beloved to me.
