Tell them: "O men, it's my duty to warn you clearly." 49 So those who believe (in the Oneness of Allah Islamic Monotheism) and do righteous good deeds, for them is forgiveness and Rizqun Karim (generous provision, i.e. Paradise). 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 so that those who are given knowledge may realize that this is the truth from your Lord and thus believe in it, and so that in their hearts they may humbly submit to Him. God will surely guide the faithful to a straight path. 54 But those who disbelieve will not cease to be in doubt of it until the Hour comes upon them unexpectedly or there comes to them the punishment of a barren Day. 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 But as for the unbelievers, who cried lies to Our signs; for them awaits a humbling chastisement. 57
