Say (Prophet Muhammad): 'O people, I have been sent to warn you plainly. 49 And those who have believed and done righteous deeds - for them is forgiveness and noble provision. 50 And (as for) those who strive to oppose Our communications, they shall be the inmates of the flaming fire. 51 Never did We send a Messenger or a Prophet before you, but; when he did recite the revelation or narrated or spoke, Shaitan (Satan) threw (some falsehood) in it. But Allah abolishes that which Shaitan (Satan) throws in. Then Allah establishes His Revelations. And Allah is All-Knower, All-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 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 The unbelievers will not cease to be in doubt about it until the Hour suddenly comes upon them, or the chastisement of an ominous day overtakes them. 55 For Allah only is the kingship on that day; He will judge between them; so those who believed and did good deeds are in Gardens of content. 56 But those who did not believe and called Our revelations lies, will be given disgraceful punishment. 57
