(Muhammad), tell them, "People, I am giving you a clear warning. 49 Those who believe and do good works, for them is pardon and a rich 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 that He may make what Satan casts a trial for those in whose hearts is sickness, and those whose hearts are hard; and surely the evildoers are in wide schism; 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 And those who disbelieve will not cease to be in doubt thereof until the Hour cometh upon them on a sudden, or there cometh upon them the torment of a Barren Day. 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 And those who disbelieved and belied Our signs - then these! for them will be a torment ignominous. 57
