It was narrated from An-Numan bin Bashir that his father gave him a slave as a present, then he came to the Prophet (صلی اللہ علیہ وسلم) to ask him to bear witness (to that). He said: "Have you given a present to all of your children?" He said: "No." He said: "Then take it back." This wording is that of (one of the narrators) Muhammad.
