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 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 devil includes a trial for those in whose hearts is a disease, and those whose hearts are hardened; indeed the unjust are extremely quarrelsome. 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 And those who disbelieve shall not cease to be in doubt concerning it until the hour overtakes them suddenly, or there comes on them the chastisement of a destructive 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 but those who deny the truth and deny Our signs will receive a humiliating punishment. 57
