Chapter: The stone is for illegal sexual intercourse
Narrated `Aisha:
Sa`d bin Abi Waqqas and `Abd bin Zam`a quarrelled with each other (regarding a child). The Prophet (ﷺ) said, "The boy is for you, O `Abd bin Zam`a, for the boy is for (the owner) of the bed. O Sauda ! Screen yourself from the boy." The sub-narrator, Al-Laith added (that the Prophet (ﷺ) also said), "And the stone is for the person who commits an illegal sexual intercourse."
