They question you about the spirit. Say: 'The spirit is from the command of my Lord. Except for a little knowledge you have been given nothing' 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 for Mercy from your Lord; for His favor to you is great indeed. 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 We have explained to man, in this Qur'an, every kind of similitude: yet the greater part of men refuse (to receive it) except with ingratitude! 89 And they say: "We shall not believe in you (O Muhammad SAW), until you cause a spring to gush forth from the earth for us; 90 or till thou possessest a garden of plants and vines, and thou makest rivers to gush forth abundantly all amongst it, 91 or, until you cause the sky to fall upon us in pieces, as you have claimed, or, as a surety bring Allah with the angels in front; 92 “Or you have a house of gold, or you ascend up into heaven; and even then we shall not believe in your ascent unless you send down a book upon us, which we may read”; say (O dear Prophet Mohammed – peace and blessings be upon him), “Purity is to my Lord – who am I except a human, sent by Allah?” (* These can be done, only when Allah commands.) 93
