Hazrat Ali (may Allah be pleased with him) narrates that news reached the Noble Prophet (peace and blessings be upon him) regarding a slave girl belonging to some people, that she had committed a sin. So the Prophet (peace and blessings be upon him) sent me to her and said: "Go and establish the prescribed punishment on her." So I went and found her in such a state that her blood had not yet dried. The Prophet (peace and blessings be upon him) asked: "Have you finished?" I replied: "I found her in such a state that her blood had not yet dried!" The Prophet (peace and blessings be upon him) said: "When her blood dries, then flog her." Then the Messenger of Allah (peace and blessings be upon him) instructed: "Establish the prescribed punishments on those under your authority."
