Say (O Muhammad): "O people! I have been sent to you only as a plain warner (before the Doom strikes you)." 49 Those who believe and do good works, theirs shall be forgiveness and a generous provision; 50 but those who strive to void Our verses, thinking they have escaped, shall be the people of Hell' 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 [And He allows doubts to arise] so that He might cause whatever aspersion Satan may cast [against His prophets] to become a trial for all in whose hearts is disease and all whose hearts are hardened: for, verily, all who are [thus] sinning [against themselves] are most deeply in the wrong. 53 And so those who were given knowledge may know that it is the truth from your Lord and [therefore] believe in it, and their hearts humbly submit to it. And indeed is Allah the Guide of those who have believed to a straight path. 54 The infidels will remain in doubt about it till the Hour overtakes them unawares, or the punishment of the barren day destructive should come upon them. 55 The Kingdom upon that Day shall belong to Allah. He will judge between them. Those who believe and do good works shall be in Gardens of Bliss, 56 And those who disbelieved and denied Our signs – for them will be a disgraceful punishment. 57
