Educate those less fortunate than us; Be loyal to our masters even when we are slaves; Believe in Prophet Muhammad PBUH; Do good deeds with sincerity

This hadith speaks about three different types of people that will receive double reward from Allah. The first type is someone who has a slave girl, educates her properly without violence, manumits her, and then marries her. The second type is someone from the people of the scriptures who was already a true believer but then also believes in Prophet Muhammad (PBUH). The third type is someone who is a slave but still observes Allah's Rights and Obligations and remains sincere to his master. This hadith teaches us that if we do good deeds such as educating those less fortunate than us or being loyal to our masters even when we are slaves, we will be rewarded twice by Allah for our efforts. It also shows us that it doesn't matter what religion you follow or what your social status may be; if you do good deeds with sincerity, you will be rewarded by Allah for it.
