(12) باب الْهِبَةِ لِلْوَلَدِ
Narrated An-Nu`man bin Bashir:
that his father took him to Allah's Messenger (ﷺ) and said, "I have given this son of mine a slave." The Prophet asked, "Have you given all your sons the like?" He replied in the negative. The Prophet (ﷺ) said, "Take back your gift then."
