"The Messenger of Allah said: 'Religion is sincerity (An-Nasihah).' They said: 'To whom, O Messenger of Allah?' he said: 'To Allah, to His Book, to His Messenger, to the imams of the Muslims, and to their common folk."'
Sunan an-Nasa'i Book 39, Hadith 49
← Previous Hadith "The Imam is like a shield whose orders should be obeyed when they (the Muslims) fight, and where they should seek protection. If he enjoins fear of Allah and behaves justly, then he will be rewarded, but if he enjoins otherwise, then it will be a burden (of sin) on him."
