SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 So those who believe and act righteously shall be granted forgiveness and an honourable sustenance, 50 Whereas those who strive against Our signs, seeking to defeat their purpose, shall be the inmates of the Fire. 51 We have sent no messenger or apostle before you with whose recitations Satan did not tamper. Yet God abrogates what Satan interpolates; then He confirms His revelations, for God is all-knowing and all-wise. 52 So that He may make what the Shaitan casts a trial for those in whose hearts is disease and those whose hearts are hard; and most surely the unjust are in a great opposition, 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 never cease to doubt it until the Hour overtakes them suddenly or the punishment of the Barren Day comes upon them. 55 The kingdom on that day shall be Allah's; He will judge between them; so those who believe and do good will be in gardens of bliss. 56 and the unbelievers who called Our revelations lies will suffer humiliating torment. 57
