Narrated by Sayyiduna Abu Musa (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever has a slave-girl and he gives her good education and teaches her good manners, then sets her free and marries her, for him there will be two rewards. The slave who fulfills the rights of Allah Almighty and the rights of his masters, for him there are two rewards. And the person from the People of the Book who first believed in the Shariah brought by Jesus (peace be upon him), and then believed in the Shariah brought by Muhammad (peace and blessings be upon him), for him also there are two rewards.
