Say: O people! I am only a plain warner to you. 49 Then those who believe and work righteous works - for them is forgiveness and a provision honourable. 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 That He (Allah) may make what is thrown in by Shaitan (Satan) a trial for those in whose hearts is a disease (of hypocrisy and disbelief) and whose hearts are hardened. And certainly, the Zalimun (polytheists and wrong-doers, etc.) are in an opposition far-off (from the truth against Allah's Messenger and the believers). 53 And that those who have been vouchsafed knowledge may know that it is the truth from thy Lord and may believe therein, and so their hearts may submit thereto. And verily Allah is the Guide of those who believe unto a path straight. 54 The unbelievers will not cease to be in doubt about it until the Hour suddenly comes upon them, or the chastisement of an ominous day overtakes them. 55 The order will be God's on that Day; He will judge between them. Then those who had come to believe and done the right will be in gardens of delight. 56 But as for the unbelievers, who cried lies to Our signs; for them awaits a humbling chastisement. 57
