SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 The righteously striving believers will receive forgiveness and honorable sustenance. 50 Those who try to challenge Our miracles will be the dwellers of hell." 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 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 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 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 On that Day of Dominion will be that of Allah: He will judge between them: so those who believe and work righteous deeds will be in Gardens of Delight. 56 And those who disbelieved and belied Our Verses (of this Quran), for them will be a humiliating torment (in Hell). 57
