It is narrated from Sayyiduna Tamim Dari (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "The religion is entirely sincere advice." The Companions (may Allah be pleased with them) asked: O Messenger of Allah! For whom? The Prophet (peace and blessings of Allah be upon him) said: For Allah, for His Book, for His Messenger, for the leaders of the Muslims, and for the common Muslims.
