Proclaim, “O mankind, I am for you only a clear Herald of Warning.” 49 So those who believe and act righteously shall be granted forgiveness and an honourable sustenance, 50 And those who strive against Our signs to void them -- they shall be the inhabitants of Hell. 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 He makes Satan's suggestions a trial for those whose hearts are diseased or hardened, and, surely, the wrongdoers are far gone in error, 53 And that those who have been given knowledge may know that it is the truth from thy Lord, so that they may believe therein and their hearts may submit humbly unto Him. Lo! Allah verily is guiding those who believe unto a right path. 54 But those who disbelieve will not cease to be in doubt of it until the Hour comes upon them unexpectedly or there comes to them the punishment of a barren Day. 55 On that Day all control will belong to God. He will judge between them. Those who believe and do good deeds shall enter the Gardens of Bliss, 56 While those who disbelieved and denied Our revelations, for them will be a shameful doom. 57
