What! is it a wonder to the people that We revealed to a man from among themselves, saying: Warn the people and give good news to those who believe that theirs is a footing of firmness with their Lord. The unbelievers say: This is most surely a manifest enchanter.

Say: The Holy spirit has revealed it from your Lord with the truth, that it may establish those who believe and as a guidance and good news for those who submit.

Or you should have a house of gold, or you should ascend into heaven, and we will not believe in your ascending until you bring down to us a book which we may read. Say: Glory be to my Lord; am I aught but a mortal messenger?

And We have not made the wardens of the fire others than angels, 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 unbelievers may say: What does Allah mean by this parable? Thus does Allah make err whom He pleases, and He guides whom He pleases, and none knows the hosts of your Lord but He Himself; and this is naught but a reminder to the mortals.
