It is narrated from Hazrat Nu'man (may Allah be pleased with him) that his father gave him a gift. His mother said to his father, "Make someone a witness over this gift for my son." His father went to the service of the Prophet Muhammad (peace and blessings be upon him) and mentioned this matter. The Prophet Muhammad (peace and blessings be upon him) asked him, "Have you given all your sons the same as you have given to him?" He replied, "No." So the Prophet Muhammad (peace and blessings be upon him) said, "Go back."
