What did the Prophet Muhammad (saw) say about three people who have a double reward?
      Narrated Abu Burda's father:                          Allah's Apostle said "Three persons will have a double reward:     1. A Person from the people of the scriptures who believed in his      prophet (Jesus or Moses) and then believed in the Prophet Muhammad (i      .e. has embraced Islam).     2. A slave who discharges his duties to Allah and his master.     3. A master of a woman-slave who teaches her good manners and educates     her in the best possible way (the religion) and manumits her and then      marries her."
