Narrated Abdullah bin Umar (may Allah be pleased with them): The Prophet (peace and blessings of Allah be upon him) sent out an army and appointed Usama bin Zaid (may Allah be pleased with him) as its commander. Some people objected to his being made the commander. The Prophet (peace and blessings of Allah be upon him) said, "If you are objecting to his being made the commander today, then before this you also objected to his father's being made the commander. By Allah, he (Zaid, may Allah be pleased with him) was worthy of leadership and was the dearest to me, and this one (Usama, may Allah be pleased with him) is now the dearest to me after him."
