We have not appointed any one but angels as keepers of Hell, and their number that We have fixed is to make it a means of contention for disbelievers, so that those who were given the Book may be certain, and the faith of the believers may have greater increase, and the people of the Book and believers may not be deceived, and the sceptics and infidels may say: “What does God mean by this parable?” That is how God leads whosoever He will astray, and guides whosoever He will. None knows the armies of your Lord save Him self. This is no more than reminder for mankind.
