And We have appointed only angels as guards of Hell. And We have fixed their number only as a trial for the disbelievers so that the People of the Book may believe with certitude (that the Qur’an and the Prophethood of Muhammad [blessings and peace be upon be upon him] is a Truth because the same number was given in their Scriptures as well), and that the faith of the believers may further be strengthened (with this confirmation), and that the people of the Book and the believers may not doubt (its trueness), and that those having disease (of hypocrisy) in their hearts and the disbelievers may say: ‘What does Allah intend by this example (of number)?’ In this way Allah holds astray whom He wills and guides aright whom He wills (with the same stroke). And no one knows the armies of your Lord except Him. And this (description of Hell is nothing else) but an admonition to mankind.
