They ask you about revelation. Say, revelation is by the command of your Lord, and that you have been given but little knowledge. 85 And if We listed, We could surely take away that which We have revealed unto thee; then thou wilt not find in respect thereof against Us as trustee. 86 (It is naught) save mercy from thy Lord. Lo! His kindness unto thee was ever great. 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 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 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 you should cause the heaven to come down upon us in pieces as you think, or bring Allah and the angels face to face (with us). 92 Or you should have a house of gold, or you should ascend into heaven, and we will not believe in your ascending until you bring down to us a book which we may read. Say: Glory be to my Lord; am I aught but a mortal apostle? 93
