"And certainly We have made clear for men in this Qur'an every kind of description, but most men consent to naught save denying. And they say: We will by no means believe in thee, till thou cause a spring to gush forth from the earth for us, Or thou have a garden of palms and grapes in the midst of which thou cause rivers to flow forth abundantly, Or thou cause the heaven to come down upon us in pieces, as thou thinkest, or bring Allah and the angels face to face (with us), Or thou have a house of gold, or thou ascend into heaven. And we will not believe in thy ascending till thou bring down to us a book we can read. Say: Glory to my Lord am I aught but a mortal messenger? And nothing prevents people from believing, when the guidance comes to them, except that they say: Has Allah raised up a mortal to be a messenger? Say: Had there been in the earth angels walking about secure, We would have sent down to them from the heaven an angel as messenger. Say: Allah suffices for a witness between me and you. Surely He is ever Aware of His servants, Seeing. And he whom Allah guides, he is on the right way; and he whom He leaves in error, for them thou wilt find no guardians besides Him. And We shall gather them together on the day of Resurrection on their faces, blind and dumb and deaf. Their abode is hell. Whenever it abates, We make them burn the more. This is their retribution because they disbelieve in Our messages and say: When we are bones and decayed particles, shall we then be raised up into a new creation? See they not that Allah, Who created the heavens and the earth, is able to create the like of them? And He has appointed for them a term, whereof there is no doubt. But the wrongdoers consent to naught but denying."
