It is narrated from Hazrat Aisha (may Allah be pleased with her) that the Noble Prophet (peace and blessings be upon him) said: When a slave-girl commits adultery, flog her; then if she commits this sin again, flog her again; then if she commits this sin again, flog her again; then if after that she commits this sin again, flog her and then sell her, even if it is in exchange for a rope.
