Narrated Abu Huraira:
The Prophet said, “If a lady slave commits illegal sexual intercourse and she is proved guilty of il –
legal sexual intercourse, then she should be flogged (fifty stripes) but she should not be admonished;
and if she commits illegal sexual intercourse again, then she should be flogged again but should not
be admonished; and if she commits illegal sexual intercourse for the third time, then she should be
sold even for a hair rope.”
