SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 For those who believe and do the right is forgiveness and gracious provision. 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 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 so those who were given knowledge may know that it is the truth from your Lord and [therefore] believe in it, and their hearts humbly submit to it. And indeed is Allah the Guide of those who have believed to a straight path. 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 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 they who disbelieved and denied Our signs - for those there will be a humiliating punishment. 57
