They ask you concerning the soul; proclaim “The soul is an entity by the command of my Lord, and you have not received knowledge except a little.” 85 If We willed, We could take away that We have revealed to thee, then thou wouldst find none thereover to guard thee against Us, 86 Except [We have left it with you] as a mercy from your Lord. Indeed, His favor upon you has ever been great. 87 Say: "If all mankind and all invisible beings would come together with a view to producing the like of this Qur'an, they could not produce its like even though they were to exert all their strength in aiding one another!" 88 We have indeed turned about for men in this Koran every manner of similitude; yet most men refuse all but unbelief. 89 And say: "We will not believe you until you make a spring of water gush forth from the earth for us; 90 "Or you have a garden of date-palms and grapes, and cause rivers to gush forth in their midst abundantly; 91 or cause the sky to fall on us in pieces as you claimed, or bring Allah and the angels before us, face to face; 92 Or you have a house of gold or you ascend into the sky. And [even then], we will not believe in your ascension until you bring down to us a book we may read." Say, "Exalted is my Lord! Was I ever but a human messenger?" 93
