Chapter 31: The Book of Presents
It was narrated from An-Nu' man bin Bashir that his father Bashir bin Sa' d brought An-Nu' man with him and said: "O Messenger of Allah, I have given this son of mine a slave who belonged to me as a present." The Messenger of Allah said: "Have you given a present to all your children?" He said: "No." He said: "Then take (your present) back."
