Say: O mankind! I am only a plain warner unto you. 49 Those who believe and do good works, theirs shall be forgiveness and a generous 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 And We did not send before you any messenger or prophet except that when he spoke [or recited], Satan threw into it [some misunderstanding]. But Allah abolishes that which Satan throws in; then Allah makes precise His verses. And Allah is Knowing and 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 they who have been given knowledge may know that it is the truth from thy Lord and believe in it, and so their hearts be humble unto Him; and assuredly God ever guides those who believe to a straight path. 54 And those who disbelieve will not cease to be in doubt thereof until the Hour come upon them unawares, or there come unto them the doom of a disastrous day. 55 On that Day of Dominion will be that of Allah: He will judge between them: so those who believe and work righteous deeds 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
