SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 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 He may make that which the devil proposeth a temptation for those in whose hearts is a disease, and those whose hearts are hardened - Lo! the evil-doers are in open schism - 53 And that those who have been given the knowledge may know that it is the truth from your Lord, so they may believe in it and their hearts may be lowly before it; and most surely Allah is the Guide of those who believe into a right path. 54 The unbelievers will continue to doubt the Quran until the Hour of Doom suddenly sizes them or the torment of the last day strikes them. 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 Verses (of this Quran), for them will be a humiliating torment (in Hell). 57
