They ask thee concerning the Spirit (of inspiration). Say: "The Spirit (cometh) by command of my Lord: of knowledge it is only a little that is communicated to you, (O men!)" 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 by the mercy of your Lord. He has certainly bestowed great favors on you. 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 certainly We have explained for men in this Quran every kind of similitude, but most men do not consent to aught but denying. 89 They said: "We shall not accept your Message until you cause a spring to gush forth for us from the earth; 90 “Or you have a garden of date-palms and grapes, and you make gushing rivers to flow in it.” 91 "Or you cause the heaven to fall upon us in pieces, as you have pretended, or you bring Allah and the angels before (us) face to face; 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
