An-Nu'man bin Bashir Al-Ansari narrated that his mother, the daughter of Rawahah, asked his father to give some of his wealth to her son. He deferred that for a year, then he decided to give it to him. She said:
I will not be pleased until you ask the Messenger of Allah to bear witness. He said: O Messenger of Allah, the mother of this boy, the daughter of Rawahah, insisted that I give a gift to him. The Messenger of Allah said: O Bashir, do you have any other children besides this one? He said: Yes. The Messenger of Allah said: Have you given all of them a gift like that which you have given to this son of yours? He said: No. The Messenger of Allah said: Then do not ask me to bear witness, for I will not bear witness to unfairness.
