A man had relations with his wife's slave girl, and the matter was brought before the Messenger of Allah ﷺ. He said, "If he forced her, she is freed at his expense, and he must give her mistress a replacement of equal value. If she consented willingly, she belongs to her mistress, and he must also give her mistress one like her from his own property."
أخبرنا محمد بن عبد الله بن بزيع قال حدثنا يزيد قال حدثنا سعيد عن قتادة عن الحسن
أن رجلا غشي جارية لامرأته فرفع ذلك إلى رسول الله ﷺ فقال إن كان استكرهها فهي حرة من ماله وعليه الشروى لسيدتها وإن كانت طاوعته فهي لسيدتها ومثلها من ماله
