Say: O mankind! I am only a plain warner unto you. 49 So those who believe and act righteously shall be granted forgiveness and an honourable sustenance, 50 Whereas those who strive against Our signs, seeking to defeat their purpose, shall be the inmates of the Fire. 51 Never have We sent a Messenger or a Prophet before you, but when he hoped, satan tampered with his hope. But Allah supersedes the tampering of satan and confirms His verses. And Allah is the Knower, the Wise. 52 (This He permits) in order that He makes satan's interjections a temptation for those in whose hearts is a sickness and those whose hearts are hardened and the harmdoers are in a wide schism, 53 And that those who have been given knowledge may know that it is the truth from thy Lord, so that they may believe therein and their hearts may submit humbly unto Him. Lo! Allah verily is guiding those who believe unto a right path. 54 The unbelievers will continue to doubt the Quran until the Hour of Doom suddenly sizes them or the torment of the last day strikes them. 55 The Kingdom upon that Day shall belong to Allah. He will judge between them. Those who believe and do good works shall be in Gardens of Bliss, 56 And they who disbelieved and denied Our signs - for those there will be a humiliating punishment. 57
