Volume 5, Book 57, Number 77:
Narrated ‘Abdullah bin ‘Umar:
The Prophet sent an army under the command of Usama bin Zaid. When some people criticized
his leadership, the Prophet said, “If you are criticizing Usama’s leadership, you used to criticize his
father’s leadership before. By Allah! He was worthy of leadership and was one of the dearest persons
to me, and (now) this (i.e. Usama) is one of the dearest to me after him (i.e. Zaid).”
