Proclaim, “O mankind, I am for you only a clear Herald of Warning.” 49 So those who believed and did good deeds, for them are forgiveness, and an excellent sustenance. 50 but those who strive to void Our verses, thinking they have escaped, shall be the people of Hell' 51 Never did We send a messenger or a prophet before thee, but, when he framed a desire, Satan threw some (vanity) into his desire: but Allah will cancel anything (vain) that Satan throws in, and Allah will confirm (and establish) His Signs: for Allah is full of Knowledge and Wisdom: 52 He makes Satan's suggestions a trial for those whose hearts are diseased or hardened, and, surely, the wrongdoers are far gone in error, 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 will not cease to be in doubt about it (this Quran) until the Hour comes suddenly upon them, or there comes to them the torment of the Day after which there will be no night (i.e. the Day of Resurrection). 55 [All] sovereignty that Day is for Allah; He will judge between them. So they who believed and did righteous deeds will be in the Gardens of Pleasure. 56 but those who deny the truth and deny Our signs will receive a humiliating punishment. 57
