SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 "Those who believe and work righteousness, for them is forgiveness and a sustenance most generous. 50 And those who strive against Our signs to void them -- they shall be the inhabitants 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 This is in order to make the interpolations of Satan a test for those whose hearts are diseased and hardened: Surely the sinners have gone far in dissent. 53 And that those who have been given the knowledge may know that it is the truth from your Lord, so they may believe in it and their hearts may be lowly before it; and most surely Allah is the Guide of those who believe into a right path. 54 The infidels will remain in doubt about it till the Hour overtakes them unawares, or the punishment of the barren day destructive should come upon 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 But as for the unbelievers, who cried lies to Our signs; for them awaits a humbling chastisement. 57
