Tell them: "O men, it's my duty to warn you clearly." 49 Those who believe and do good works, theirs shall be forgiveness and a generous provision; 50 And (as for) those who strive to oppose Our communications, they shall be the inmates of the flaming 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 That He may make the suggestions thrown in by Satan, but a trial for those in whose hearts is a disease and who are hardened of heart: verily the wrong-doers are in a schism far (from the Truth): 53 and that they who have been given knowledge may know that it is the truth from thy Lord and believe in it, and so their hearts be humble unto Him; and assuredly God ever guides those who believe to a straight path. 54 The unbelievers will continue to doubt the Quran until the Hour of Doom suddenly sizes them or the torment of the last day strikes them. 55 The Kingdom upon that day shall belong to God, and He shall judge between them. As for those who believe, and do deeds of righteousness, they 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
