КОРАН (английский перевод) - 74.31

We have appointed none but angels to guard the Fire, and made their number only as a trial for the unbelievers, so that those to whom the Book was given are certain and those who believe increase in belief. And that those who were given the Book, and those who believe will not be in doubt. And that those in whose hearts there is a sickness, together with the unbelievers, may say: 'What did Allah intend by this as an example? ' As such, Allah leaves in error whom He will and He guides whomsoever He will. None knows the hosts of your Lord except He. This is no more than a Reminder to humans.
