Say, "O people, I am sent only to give you clear warning." 49 Those who believe, and do deeds of righteousness -- theirs shall be forgiveness and generous provision. 50 And those who endeavour in respect of Our signs to frustrate them - those shall be the fellows of Flaming Fire. 51 Never have We sent a Messenger or a Prophet before you, but when he hoped, satan tampered with his hope. But Allah supersedes the tampering of satan and confirms His verses. And Allah is the Knower, the Wise. 52 [That is] so He may make what Satan throws in a trial for those within whose hearts is disease and those hard of heart. And indeed, the wrongdoers are in extreme dissension. 53 And that those on whom knowledge has been bestowed may learn that the (Qur'an) is the Truth from thy Lord, and that they may believe therein, and their hearts may be made humbly (open) to it: for verily Allah is the Guide of those who believe, to the Straight Way. 54 And those who disbelieve will not cease to be in doubt about it (this Quran) until the Hour comes suddenly upon them, or there comes to them the torment of the Day after which there will be no night (i.e. the Day of Resurrection). 55 For Allah only is the kingship on that day; He will judge between them; so those who believed and did good deeds are in Gardens of content. 56 And (as for) those who disbelieve in and reject Our communications, these it is who shall have a disgraceful chastisement. 57
