They ask you about revelation. Say, revelation is by the command of your Lord, and that you have been given but little knowledge. 85 Had We wanted, We could have removed the Spirit through whom We sent you revelation. Then you would not have found anyone to intercede with Us for you 86 Except as a Mercy from your Lord. Verily! His Grace unto you (O Muhammad SAW) is ever great. 87 Say, "If all men and jinn gathered together to produce the like of this Quran, they could not produce one like it, however much they helped one another." 88 For, indeed, many facets have We given in this Qur'an to every kind of lesson [designed] for [the benefit of] mankind! However, most men are unwilling to accept anything but blasphemy 89 And they say: We will not put faith in thee till thou cause a spring to gush forth from the earth for us; 90 “Or you have a garden of date-palms and grapes, and you make gushing rivers to flow in it.” 91 "Or thou cause the sky to fall in pieces, as thou sayest (will happen), against us; or thou bring Allah and the angels before (us) 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
