It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: A righteous slave receives a double reward. By Him in Whose hand is the life of Abu Hurairah (may Allah be pleased with him), if it were not for striving in the way of Allah, Hajj to the House of Allah, and service to my mother, I would have preferred to die in the state of slavery.
