English translation
3011. Narrated Abū Burda's father: The Prophet ﷺ said, "Three persons will get their reward twice: (1) a person who has a slave-girl and he educates her properly and teaches her good manners properly (without violence) and then manumits and marries her. Such a person will get a double reward; (2) a believer from the people of the Scriptures (Jews and Christians) who has been a true believer and then he believes in the Prophet (Muḥammad) ﷺ. Such a person will get a double reward; (3) (The third is) a slave who fulfils his duty to Allāh and is sincere and dutiful to his master [will (also) get a double reward]." (See H. 97, 5083)
