It was narrated that Abu Hurairah, Zaid bin Khalid and Shibl said: “We were with the Prophet (ﷺ) and a man asked him about a slave woman who commits fornication (again), whip her, even if that is for a rope of hair.' ”
Aishah narrated that the Messenger of Allah(ﷺ) said: “If a slave woman commits fornication then whip her, and if she commits fornication then whip her, and if she commits fornication then whip her, then sell her even if that is for a rope.”
