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