Say: 'O men, I am only for you a plain warner.' 49 "Those who believe and work righteousness, for them is forgiveness and a sustenance most generous. 50 But the ones who strove against Our verses, [seeking] to cause failure - those are the companions of Hellfire. 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 is] so He may make what Satan throws in a trial for those within whose hearts is disease and those hard of heart. And indeed, the wrongdoers are in extreme dissension. 53 And that those who have been vouchsafed knowledge may know that it is the truth from thy Lord and may believe therein, and so their hearts may submit thereto. And verily Allah is the Guide of those who believe unto a path straight. 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 But those who did not believe and called Our revelations lies, will be given disgraceful punishment. 57
