Proclaim, “O mankind, I am for you only a clear Herald of Warning.” 49 Those who believe and do good works, theirs shall be forgiveness and a generous provision; 50 And those who endeavour in respect of Our signs to frustrate them - those shall be the fellows of Flaming Fire. 51 We sent not ever any Messenger or Prophet before thee, but that Satan cast into his fancy, when he was fancying; but God annuls what Satan casts, then God confirms His signs -- surely God is All-knowing, All-wise -- 52 So that He may make what the Shaitan casts a trial for those in whose hearts is disease and those whose hearts are hard; and most surely the unjust are in a great opposition, 53 (He also does this) in order that those endowed with knowledge may know that it is the Truth from your Lord and that they may have faith in it and their hearts may humble themselves before Him. Verily Allah always directs those that believe to the Right Way. 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 The kingdom on that day shall be Allah's; He will judge between them; so those who believe and do good will be in gardens of bliss. 56 but those who deny the truth and deny Our signs will receive a humiliating punishment. 57
