Say: "O men! I am (sent) to you only to give a Clear Warning: 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 While those who strive to thwart Our revelations, such are rightful owners of the Fire. 51 Satan would try to tamper with the desires of every Prophet or Messenger whom We sent. Then God would remove Satan's temptations and strengthen 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 that the people given the knowledge may know that it is the truth from your Lord, in order that they may accept faith in it, therefore their hearts may humble before Him; and indeed Allah will guide the believers on the 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 For Allah only is the kingship on that day; He will judge between them; so those who believed and did good deeds are in Gardens of content. 56 But as for the unbelievers, who cried lies to Our signs; for them awaits a humbling chastisement. 57
