Abdullah bin Dinar heard Ibn Umar (may Allah be pleased with them both) saying: The Prophet (peace and blessings be upon him) sent out an army and appointed Usamah bin Zayd as its commander. People criticised his command, so the Prophet (peace and blessings be upon him) said: "If you criticise his command, you already criticised the command of his father before. By Allah, he (his father) was worthy of command, and he was among the most beloved of people to me, and this one is among the most beloved of people to me after him."
