Tell them: "O men, it's my duty to warn you clearly." 49 Those who believe, and do deeds of righteousness -- theirs shall be forgiveness and generous provision. 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 [And He allows doubts to arise] so that He might cause whatever aspersion Satan may cast [against His prophets] to become a trial for all in whose hearts is disease and all whose hearts are hardened: for, verily, all who are [thus] sinning [against themselves] are most deeply in the wrong. 53 And so that the people given the knowledge may know that it is the truth from your Lord, in order that they may accept faith in it, therefore their hearts may humble before Him; and indeed Allah will guide the believers on the Straight Path. 54 whereas those who are bent on denying the truth will not cease to be in doubt about Him until the Last Hour comes suddenly upon them and [supreme] suffering befalls them on a Day void of all hope. 55 The Kingdom upon that day shall belong to God, and He shall judge between them. As for those who believe, and do deeds of righteousness, they shall be in Gardens of Bliss. 56 and the unbelievers who called Our revelations lies will suffer humiliating torment. 57
