Say, "The Spirit is at my Lord's command, and you have been granted but little knowledge." 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 Unless your Lord have mercy. His blessings on you are great indeed. 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 assuredly We have variously propounded for mankind in this Qur'an every kind of similitude, yet most men have refused everything except infidelity. 89 They have said, "We shall never believe you until you cause a spring to gush forth from the earth, 90 Or thou have a garden of date-palms and grapes, and cause rivers to gush forth therein abundantly; 91 or, until you cause the sky to fall upon us in pieces, as you have claimed, or, as a surety bring Allah with the angels in front; 92 or (show us) that you have a well adorned house of your own, or climb into the sky. We shall never believe that you have climbed into the sky until you bring us a book that we can read." Say, "All glory belongs to my Lord. Am I more than a mortal Messenger?" 93
