Sayyiduna Tamim Dari (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings of Allah be upon him) said: "The religion is sincerity (good counsel)." He said this three times. The people asked, "O Messenger of Allah (peace and blessings of Allah be upon him)! For whom?" The Noble Prophet (peace and blessings of Allah be upon him) replied: "For Allah, for His Book, for His Messenger, for the leaders of the Muslims (the narrator is in doubt, or perhaps these are the words) for the leaders of the believers, and for their common people (to be sincere to them)."
