Say (Prophet Muhammad): 'O people, I have been sent to warn you plainly. 49 Then those who believe and work righteous works - for them is forgiveness and a provision honourable. 50 whereas those who strive against Our Signs, seeking to profane them, they are the friends of the Fire! 51 We sent not ever any Messenger or Prophet before thee, but that Satan cast into his fancy, when he was fancying; but God annuls what Satan casts, then God confirms His signs -- surely God is All-knowing, 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 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 Those who deny the truth will continue in doubt until the [Last] Hour suddenly comes upon them or the scourge of the woeful Day descends upon them. 55 The kingdom on that day shall be Allah's; He will judge between them; so those who believe and do good will be in gardens of bliss. 56 But as for the unbelievers, who cried lies to Our signs; for them awaits a humbling chastisement. 57
