It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) said: When a slave obeys both his Lord and his master, he receives a double reward. The narrator says: When Sayyiduna Abu Rafi’ (may Allah be pleased with him) was set free, he began to weep. When he was asked what was making him cry, he said: I used to have two rewards, and now one of them has ended.
