Silsilat al-Ahadith al-Sahihah

Aamir says: I heard Sayyiduna Nu’man bin Bashir (may Allah be pleased with him) while he was delivering a sermon: My father gave me a gift in charity. Sayyidah Amrah bint Rawahah said: I will not be pleased until you make the Messenger of Allah (peace and blessings be upon him) a witness to this. So Sayyiduna Bashir (may Allah be pleased with him) came to the Messenger of Allah (peace and blessings be upon him) and said: I have given charity to my son, and Amrah bint Rawahah has told me that she will not be pleased until you make the Messenger of Allah (peace and blessings be upon him) a witness to it. The Prophet (peace and blessings be upon him) asked him: “Do you have other sons besides him?” He said: Yes. The Prophet (peace and blessings be upon him) said: “Have you given all of them the same as you have given him?” He said: No. The Prophet (peace and blessings be upon him) said: “This is injustice; do not make me a witness to injustice. Fear Allah and be just among your children, just as you like them all to behave kindly towards you equally.”
