Hazrat Abu Huraira (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: A slave who is owned by someone and is righteous will receive a double reward. And Hazrat Abu Huraira (may Allah be pleased with him) said: By Him in Whose hand is my soul! If it were not for striving in the path of Allah, Hajj, and serving my mother (preventing me), I would have preferred to die as a slave.
