Say, "O people, I am only to you a clear warner." 49 So those who believe and act righteously shall be granted forgiveness and an honourable sustenance, 50 But those who strive against Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), to frustrate and obstruct them, they will be dwellers of the Hell-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 that those on whom knowledge has been bestowed may learn that the (Qur'an) is the Truth from thy Lord, and that they may believe therein, and their hearts may be made humbly (open) to it: for verily Allah is the Guide of those who believe, to the Straight Way. 54 And those who disbelieve shall not cease to be in doubt concerning it until the hour overtakes them suddenly, or there comes on them the chastisement of a destructive day. 55 On that day it is God who will be the Absolute King and Judge of (mankind). The righteously striving believers will go to Paradise 56 But those who did not believe and called Our revelations lies, will be given disgraceful punishment. 57
