Say thou: mankind! I am unto you only a warner manifest. 49 So those who believed and did good deeds, for them are forgiveness, and an excellent sustenance. 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 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 At the same time those who have been given knowledge may know that this is the truth from your Lord, and come to believe in it, and their hearts become submissive to Him. Verily God guides those who believe, to the even 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 On that day it is God who will be the Absolute King and Judge of (mankind). The righteously striving believers will go to Paradise 56 But as for the unbelievers, who cried lies to Our signs; for them awaits a humbling chastisement. 57
