And they ask thee regarding the spirit; say thou: the spirit is by the command of my Lord, and ye have not been vouchsafed of knowledge save a little. 85 If We pleased, We would certainly take away that which We have revealed to you, then you would find no guardian for you against Us, 86 (Whatever you have received) is nothing but grace from your Lord. Indeed His favour to you is great. 87 Proclaim, “If all mankind and jinns agree to bring an equivalent to the Qur’an, they will not be able to bring its equal – even if they were to help each other.” 88 And indeed We have fully explained to mankind, in this Quran, every kind of similitude, but most mankind refuse (the truth and accept nothing) but disbelief. 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 (show) us that you have your own garden of palm trees and vines with flowing streams therein, 91 Or you make the heaven fall upon us in fragments as you have claimed or you bring Allah and the angels before [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
