Narrated `Abdullah bin `Umar:
Allah's Messenger (s.a.w.a.) sent troops appointed Usama bin Zaid as their commander. The people criticized his leadership. Allah's Messenger (s.a.w.a.) got up and said, "If you (people) are criticizing his (i.e. Usama's) leadership you used to criticize the leadership of his father before. By Allah, he (i.e. Zaid) deserved the leadership indeed, and he used to be one of the most beloved persons to me, and now this (i.e. his son, Usama) is one of the most beloved persons to me after him."
Ibn 'Umar reported that Allah's Messenger (s.a.w.a.) sent an expedition and appointed Usama b. Zaid as its chief. The people objected to his command, whereupon Allah's Messenger (s.a.w.a.) stood up and said:
You object to his command and before this you objected to the command of his father (Zaid). By Allah, he was fit as the commander and he was one of the dearest of persons to me and after him, behold! this one (Usama) is one of the dearest of persons to me.
Narrated Ibn 'Umar:
that the Messenger of Allah (s.a.w.a.) sent and army and put Usamah bin Zaid in charge of them. So the people contested his leadership, so the Prophet (s.a.w.a.) said: 'If you contest his leadership, then you did contest the leadership of his father before him. And indeed, by Allah, he was certainly fit for leadership, and he was of the most beloved of people to me, and this one is among the most beloved of people to me after him.'"
