Say: "O men! I am (sent) to you only to give a Clear Warning: 49 For those who believe and do the right is forgiveness and gracious 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 This is in order to make the interpolations of Satan a test for those whose hearts are diseased and hardened: Surely the sinners have gone far in dissent. 53 And that those who have been given knowledge may know that it (this Quran) is the truth from your Lord, and that they may believe therein, and their hearts may submit to it with humility. And verily, Allah is the Guide of those who believe, to the Straight 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 [All] sovereignty that Day is for Allah; He will judge between them. So they who believed and did righteous deeds will be in the Gardens of Pleasure. 56 but those who deny the truth and deny Our signs will receive a humiliating punishment. 57
