It was narrated from An-Nu'man that his father brought him to the Prophet to bear witness to a present that he gave to him. He said: Have you given all your children a present like that which you have given to him? He said: No. He said: I will not bear witness to anything. Will it not please you if they were all to treat you with equal respect? He said: Of course. He said: Then no (I will not do it).
