They are asking thee concerning the Spirit. Say: The Spirit is by command of my Lord, and of knowledge ye have been vouchsafed but little. 85 If We pleased We could take away what We have revealed to you. Then you will not find any one to plead for it with Us, 86 except by the mercy of your Lord. He has certainly bestowed great favors on you. 87 Say: Verily, though mankind and the jinn should assemble to produce the like of this Qur'an, they could not produce the like thereof though they were helpers one of another. 88 And indeed We have illustrated all kinds of examples in the Qur’an for mankind – so most men did not accept, except to be ungrateful. 89 They have said, "We shall never believe you until you cause a spring to gush forth from the earth, 90 or that there be a garden of palms and vines for you and then you cause rivers to abundantly flow forth through them; 91 Or you should cause the heaven to come down upon us in pieces as you think, or bring Allah and the angels face to face (with us). 92 or (show us) that you have a well adorned house of your own, or climb into the sky. We shall never believe that you have climbed into the sky until you bring us a book that we can read." Say, "All glory belongs to my Lord. Am I more than a mortal Messenger?" 93
