It is narrated from Sayyiduna Nu’man bin Bashir (may Allah be pleased with both of them), he says: My father, Sayyiduna Bashir (may Allah be pleased with him), gave me a gift. My mother demanded from him that he make the Messenger of Allah (peace and blessings be upon him) a witness to this gift. So he took my hand and set out with me until we reached the Messenger of Allah (peace and blessings be upon him). He said: O Messenger of Allah! The mother of this child first demanded from me that I give him a gift, and now her demand is that I make you a witness to it, so I have come to you to make you a witness. The Messenger of Allah (peace and blessings be upon him) said: Wait a moment, do you have any other children? He said: Yes. The Messenger of Allah (peace and blessings be upon him) said: Then have you given each of them this gift? He said: No. The Messenger of Allah (peace and blessings be upon him) said: Then there is no need to make me a witness, I cannot be a witness to injustice. It is the right of your sons over you that you do justice among them.
