Hadith 2789
Sayyiduna Ibn Umar (may Allah be pleased with them both) said: The Messenger of Allah (peace and blessings be upon him) said: “The religion is (all about) sincere advice.” We asked: O Messenger of Allah (peace and blessings be upon him)! Sincere advice to whom? He (peace and blessings be upon him) said: “To Allah, to His Messenger, to His Book, to the leaders of the Muslims, and to the common Muslims.”
