The Messenger of Allah ﷺ said, "Whoever has a slave girl and raises her with excellent upbringing, teaches her with excellent instruction, then frees her and marries her, will have two rewards. Any man from the People of the Book who believed in his prophet and then believed in Muhammad will have two rewards. Any owned slave who fulfills the right of Allah upon him and the right of his masters will have two rewards."
حدثنا عبدة بن سليمان قال ثنا صالح بن صالح عن الشعبي عن أبي بردة
قال رسول الله ﷺ من كانت له جارية فأدبها فأحسن أدبها وعلمها فأحسن تعليمها ثم أعتقها وتزوجها فله أجران وأيما رجل من أهل الكتاب آمن بنبيه وآمن بمحمد فله أجران وأيما عبد مملوك أدى حق الله عز وجل عليه وحق مواليه فله أجران
