It is narrated from Hazrat Nu'man (may Allah be pleased with him) that my father took me to the service of the Holy Prophet (peace and blessings be upon him) and said, "O Messenger of Allah! Please bear witness that I have given such and such things to Nu'man." The Holy Prophet (peace and blessings be upon him) asked him, "Have you given the same to all your sons as you have given to him?" He replied, "No." So the Holy Prophet (peace and blessings be upon him) said, "Then make someone else a witness." After a little while, he said, "Do you not like that they should all be equal with you in kindness?" He said, "Why not." The Holy Prophet (peace and blessings be upon him) said, "Then it will not be so."
