"Surely he reflected and determined, But may he be destroyed how he determined! Again, may he be destroyed how he determined! Then he looked, Then frowned and scowled, Then turned back and was big with pride, Then said: This is naught but magic from of old! This is naught but the word of a mortal! I will cast him into hell. And what will make thee realize what hell is? It leaves naught, and spares naught. It scorches the mortal. Over it are nineteen. And We have made none but angels wardens of the Fire, and We have not made their number but as a trial for those who disbelieve, that those who have been given the Book may be certain and those who believe may increase in faith, and those who have been given the Book and the believers may not doubt; and that those in whose hearts is a disease and the disbelievers may say: What does Allah mean by this parable? Thus Allah leaves in error whom He pleases, and guides whom He pleases. And none knows the hosts of thy Lord but He. And this is naught but a Reminder to mortals."
