They question you about the Spirit. Say, "The Spirit is at my Lord's command, and you have been granted but little knowledge." 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 the mercy of your Lord; indeed His munificence upon you (O dear Prophet Mohammed – peace and blessings be upon him) is extremely great. 87 Say, "If all human beings and jinn were to come together to bring the equivalent of this Quran, they could not do so, even if they all were to help each other. 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 They say, 'We will not believe thee till thou makest a spring to gush forth from the earth for us, 90 Or, until you acquire an orchard of date-palm trees and grapes, and produce rivers flowing through it; 91 Or thou causest the heaven to fall upon us, as thou assertest, in pieces, or thou bringest God and the angels face to face. 92 "Or thou have a house adorned with gold, or thou mount a ladder right into the skies. No, we shall not even believe in thy mounting until thou send down to us a book that we could read." Say: "Glory to my Lord! Am I aught but a man,- a messenger?" 93
