It is narrated from Sayyiduna Ali (may Allah be pleased with him) that a slave woman of the Prophet (peace and blessings be upon him) committed the sin of fornication. The Prophet (peace and blessings be upon him) ordered me to carry out the prescribed punishment on her. When I reached her, her bleeding had not yet stopped. I informed the Prophet (peace and blessings be upon him) of this, so the Prophet (peace and blessings be upon him) said: "When her bleeding stops, then carry out the prescribed punishment on her. And remember! Carry out the prescribed punishments on your slaves as well."
