Narrated Abu Huraira (may Allah be pleased with him) that the Prophet Muhammad (peace and blessings be upon him) said: No person should say (to a slave or to anyone), "Feed your lord (meaning master), make your lord perform ablution, give your lord water to drink." Rather, one should only say, "My chief, my master." Similarly, no person should say, "My slave, my slave-girl," but rather should say, "My boy (servant), my girl (maid), my servant."
