Say: 'O men, I am only for you a plain warner.' 49 For those who believe and do the right is forgiveness and gracious provision. 50 "But those who strive against Our Signs, to frustrate them,- they will be Companions of the Fire." 51 Whenever We sent any messenger or prophet before you, and he recited anything [of Our revelation], Satan tampered with it. But God abrogates Satan's interjections and then He firmly reaffirms His revelations. God is all knowing and 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 those who were given knowledge may know that it is the truth from your Lord and [therefore] believe in it, and their hearts humbly submit to it. And indeed is Allah the Guide of those who have believed 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 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 whereas for those who were bent on denying the truth and gave the lie to Our messages, there shall be shameful suffering in store. 57
