Say: O people! I am only a plain warner to you. 49 Those who believe and do good works, theirs shall be forgiveness and a generous provision; 50 Whereas those who strive against Our signs, seeking to defeat their purpose, shall be the inmates of the Fire. 51 And We have sent before thee no apostle or prophet but when he read the Satan cast forth suggestions in respect of his reading; then Allah abolisheth that which the Satan casteth forth; then Allah confirmeth His revelations; and Allah is Knowing. Wise; 52 [And He allows doubts to arise] so that He might cause whatever aspersion Satan may cast [against His prophets] to become a trial for all in whose hearts is disease and all whose hearts are hardened: for, verily, all who are [thus] sinning [against themselves] are most deeply in the wrong. 53 At the same time those who have been given knowledge may know that this is the truth from your Lord, and come to believe in it, and their hearts become submissive to Him. Verily God guides those who believe, to the even path. 54 Those who reject Faith will not cease to be in doubt concerning (Revelation) until the Hour (of Judgment) comes suddenly upon them, or there comes to them the Penalty of a Day of Disaster. 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 And they who disbelieved and denied Our signs - for those there will be a humiliating punishment. 57
