They will question thee concerning the Spirit. Say: 'The Spirit is of the bidding of my Lord. You have been given of knowledge nothing except a little.' 85 And if We willed We could surely take away that which We have revealed to you by inspiration (i.e. this Quran). Then you would find no protector for you against Us in that respect. 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 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 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 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
