Say thou: mankind! I am unto you only a warner manifest. 49 For those who believe and do the right is forgiveness and gracious provision. 50 And (as for) those who strive to oppose Our communications, they shall be the inmates of the flaming fire. 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 (This He permits) in order that He makes satan's interjections a temptation for those in whose hearts is a sickness and those whose hearts are hardened and the harmdoers are in a wide schism, 53 And that those who have been given knowledge may know that it (this Quran) is the truth from your Lord, and that they may believe therein, and their hearts may submit to it with humility. And verily, Allah is the Guide of those who believe, to the Straight Path. 54 And the unbelievers will not cease to be in doubt of it, until the Hour comes on them suddenly, or there shall come upon them the chastisement of a barren day. 55 The Sovereignty on that day will be Allah's, He will judge between them. Then those who believed and did good works will be in Gardens of Delight, 56 And for those who reject Faith and deny our Signs, there will be a humiliating Punishment. 57
