Tell them: "O men, it's my duty to warn you clearly." 49 For those who believe and do the right is forgiveness and gracious provision. 50 Whereas those who strive against Our signs, seeking to defeat their purpose, shall be the inmates of the 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 may make that which the Satan casteth forth a temptation for those in whose heart is a disease and whose hearts are hardened - and the wrong-doers are in divergence far-off 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 A humiliating chastisement awaits those who disbelieved and denied Our Signs. 57
