Say (Prophet Muhammad): 'O people, I have been sent to warn you plainly. 49 For those who believe and do the right is forgiveness and gracious provision. 50 whereas those who strive against Our Signs, seeking to profane them, they are the friends 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 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 (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 The infidels will remain in doubt about it till the Hour overtakes them unawares, or the punishment of the barren day destructive should come upon them. 55 On that Day, all dominion shall [visibly] belong to God, He shall judge [all men and make a distinction] between them: thus, all who had attained to faith and did righteous deeds shall find themselves in gardens of bliss, 56 And those who disbelieved and belied Our signs - then these! for them will be a torment ignominous. 57
