It was narrated that 'Amir said: "I was told that Bashir bin Sa'd came to the Messenger of Allah and said: “O Messenger of Allah, my wife 'Amrah bint Rawahah told me to give a gift to her son Nu'man, and she told me to ask you to bear witness to that.' The Prophet said: “Do you have any other children?' He said: “Yes.' He said: “Have you given them something like that which you have given to this one?' He said: “No.' He said: “Then do not ask me to bear witness to unfairness””””””"
