It is narrated from Hazrat Abu Huraira (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 Huraira (may Allah be pleased with him), if it were not for striving in the way of Allah, pilgrimage to the House of Allah, and serving my mother, I would have preferred to die in the state of slavery.
