Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 Those who believe and do good works, theirs shall be forgiveness and a generous provision; 50 But the ones who strove against Our verses, [seeking] to cause failure - those are the companions of Hellfire. 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 that the people given the knowledge may know that it is the truth from your Lord, in order that they may accept faith in it, therefore their hearts may humble before Him; and indeed Allah will guide the believers on the Straight Path. 54 And the disbelievers will always be in doubt of it, to the extent that the Last Day will suddenly come upon them, or will come upon them the punishment of a day the result of which is not at all good for 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
