They question you about the spirit. Say: 'The spirit is from the command of my Lord. Except for a little knowledge you have been given nothing' 85 And if We please, We should certainly take away that which We have revealed to you, then you would not find for it any protector against Us. 86 Unless your Lord have mercy. His blessings on you are great indeed. 87 Say: 'If mankind and jinn combined together to produce the like of this Koran, they would never be able to produce one like it, not even if they were to help one another' 88 We have explained things for people in this Qur'an in diverse ways to make them understand the Message, yet most people obstinately persist in unbelief. 89 They said: "We shall not accept your Message until you 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 (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
