THREE CATEGORIES OF PEOPLE WHO WILL RECEIVE A DOUBLE REWARD H 1394 "There are three (kinds of people) who will receive a double reward. Whosoever among the People of the Book believes in his prophet, peace be upon him, and then believes in Muhammad, praise and peace be upon him. A servant who discharges his obligation due to Allah and the obligation he owes to his master. A man who owns a female servant, teaches her good manners, educates and feeds her well, and marries her." R 1394 Bukhari and Muslim with a chain up to Abu Musa Ash'ari who related that the Messenger of Allah, praise and peace be upon him, said this.
