Narrated by Nu'man bin Bashir (may Allah be pleased with him) that his father brought him to the Messenger of Allah (peace and blessings of Allah be upon him) and said, "I have given this son of mine a slave as a gift." The Prophet (peace and blessings of Allah be upon him) asked, "Have you given a similar slave to each of your other sons?" He replied, "No." The Prophet (peace and blessings of Allah be upon him) said, "Then take it back (from him)."
