Aslam

Praise be to Allah.

It is not permissible for a man to have intercourse with his slave woman

who is married; whoever does that has committed a haraam (forbidden)

action and is to be punished.

Ibn Qudaamah

said in al-Mughni: if he marries off his slave woman, then it

is forbidden for him to have intercourse with her… There is no doubt

and no dispute concerning the prohibition on his having intercourse

with her, for she is now permissible to her husband, and no woman can

be permissible to two men. If he has intercourse with her then he is

guilty of sin and must be punished. Ahmad said, he should be flogged

but not stoned, i.e., his punishment (ta’zeer) should take the form

of flogging.
