(Muhammad), tell them, "People, I am giving you a clear warning. 49 Those who believe, and do deeds of righteousness -- theirs shall be forgiveness and generous provision. 50 While those who strive to thwart Our revelations, such are rightful owners of the Fire. 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 makes Satan's suggestions a trial for those whose hearts are diseased or hardened, and, surely, the wrongdoers are far gone in error, 53 and so that those to whom knowledge has been given will know that this is the truth from your Lord and so believe in it and that their hearts will be humble to Him. Indeed, Allah will surely guide those who believe to a 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 [All] sovereignty that Day is for Allah; He will judge between them. So they who believed and did righteous deeds will be in the Gardens of Pleasure. 56 and the unbelievers who called Our revelations lies will suffer humiliating torment. 57
