Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 Those who believe and do good deeds shall be forgiven and shall receive an honourable 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 (He does this) in order that He may make the evil caused by Satan a trial for those in whose hearts there is sickness (of hypocrisy), whose hearts are hard (and vitiated). Surely these wrong-doers have gone too far in their dissension. 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 The unbelievers will not cease to be in doubt about it until the Hour suddenly comes upon them, or the chastisement of an ominous day overtakes 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 And those who disbelieved and denied Our signs – for them will be a disgraceful punishment. 57
