They ask you about "the spirit". Say: "The spirit descends by the command of my Lord, but you have been given only a little knowledge." 85 Had We willed, We could take away what We have revealed to you, then you would find none to help you in recovering it from Us. 86 Except for Mercy from thy Lord: for his bounty is to thee (indeed) great. 87 Say: "If the whole of mankind and Jinns were to gather together to produce the like of this Qur'an, they could not produce the like thereof, even if they backed up each other with help and support. 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 They say: "We shall not believe in thee, until thou cause a spring to gush forth for us from the earth, 90 or, until you own a garden of palms and vines and cause rivers to gush forth with abundant water in them; 91 or cause the sky to fall into pieces on us - as you believe you can - or bring God and the angels face to face with us, 92 "Or you have a house of adornable materials (like silver and pure gold, etc.), or you ascend up into the sky, and even then we will put no faith in your ascension until you bring down for us a Book that we would read." Say (O Muhammad SAW): "Glorified (and Exalted) be my Lord (Allah) above all that evil they (polytheists) associate with Him! Am I anything but a man, sent as a Messenger?" 93
