Tell them: "O men, it's my duty to warn you clearly." 49 So those who believed and did good deeds, for them are forgiveness, and an excellent sustenance. 50 But those who try to defeat Our signs are people of Hell. 51 Yet whenever We sent forth any apostle or prophet before thee, and he was hoping [that his warnings would be heeded,] Satan would cast an aspersion on his innermost aims: but God renders null and void whatever aspersion Satan may cast; and God makes His messages clear in and by themselves for God is all-knowing, wise. 52 (He does this) in order that He may make the evil caused by Satan a trial for those in whose hearts there is sickness (of hypocrisy), whose hearts are hard (and vitiated). Surely these wrong-doers have gone too far in their dissension. 53 And that those who have been given knowledge may know that it (this Quran) is the truth from your Lord, and that they may believe therein, and their hearts may submit to it with humility. And verily, Allah is the Guide of those who believe, to the Straight Path. 54 But those who disbelieve will not cease to be in doubt of it until the Hour comes upon them unexpectedly or there comes to them the punishment of a barren Day. 55 The Sovereignty on that day will be Allah's, He will judge between them. Then those who believed and did good works will be in Gardens of Delight, 56 And they who disbelieved and denied Our signs - for those there will be a humiliating punishment. 57
