«إن تطعنوا في إمارته فقد كنتم تطعنون في إمارة أبيه من قبل وأيم الله إن كان لخليقا بالإمارة وإن كان لمن أحب الناس إلي وإن هذا لمن أحب الناس إلي بعده وأوصيكم به فإنه من صالحيكم - يعني أسامة بن زيد -»
The Prophet (peace and blessings be upon him) said:
"If you criticise his leadership (that is, of Usamah bin Zayd), then before this you criticised the leadership of his father. By Allah, he was certainly worthy of leadership, and he was among the people most beloved to me, and after him this one (Usamah bin Zayd) too is among the people most beloved to me. I enjoin you to treat him well, for he is one of the righteous among you."
