It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When a slave fulfills the rights of Allah Almighty and the rights of his master, he will have a double reward. The narrator says: When I related this hadith to Sayyiduna Ka'b (may Allah be pleased with him), he said: There is no reckoning for such a slave, nor for a believer with little wealth.
