Say: O mankind! I am only a plain warner unto you. 49 The righteously striving believers will receive forgiveness and honorable 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 So that He may make what the devil includes a trial for those in whose hearts is a disease, and those whose hearts are hardened; indeed the unjust are extremely quarrelsome. 53 And [God renders Satan's aspersions null and void] so that they who are endowed with [innate] knowledge might know that this [divine writ] is the truth from thy Sustainer, and that they aught believe in it, and that their hearts might humbly submit unto Him. For, behold, God does guide onto a straight way those who have attained to faith 54 And those who disbelieve will not cease to be in doubt about it (this Quran) until the Hour comes suddenly upon them, or there comes to them the torment of the Day after which there will be no night (i.e. the Day of Resurrection). 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 And for those who reject Faith and deny our Signs, there will be a humiliating Punishment. 57
