The Prophet ﷺ dispatched a military expedition and placed Usama bin Zayd in command. Some people criticized his appointment, so the Prophet ﷺ said, "If you criticize his command, you also criticized his father's command before him. By Allah, he was truly worthy of command, and he was among the dearest of people to me, and this one is among the dearest of people to me after him."
بعث النبي ﷺ بعثا، وأمر عليهم أسامة بن زيد، فطعن بعض الناس في إمارته، فقال النبي ﷺ: إن تطعنوا في إمارته فقد كنتم تطعنون في إمارة أبيه من قبل، وأيم الله إن كان لخليقا للإمارة، وإن كان لمن أحب الناس إلي، وإن هذا لمن أحب الناس إلي بعده.
Bukhari narrated it in the Virtues of the Companions (3730), and Muslim in the Virtues of the Companions (2426-63), both by way of Abdullah bin Dinar, who heard Ibn Umar say, and then he related it. This is the wording of Bukhari, and the wording of Muslim is similar to it. In another wording, "The Messenger of Allah ﷺ said while he was on the pulpit, 'If you criticize his command, meaning Usama bin Zayd, then you have already criticized the command of his father before him. By Allah, he was indeed fit for it. By Allah, he was indeed the most beloved of people to me. By Allah, this one is indeed fit for it, meaning Usama bin Zayd. By Allah, he is indeed the most beloved of them to me after him. So I entrust him to you, for he is one of your righteous ones.'"Muslim narrated it in the Virtues of the Companions (2426-64) from Abu Kurayb Muhammad bin Ala, who said, Abu Usama narrated to us, from Umar meaning Ibn Hamza, from Salim, from his father, and then he related it.
