You have been given of knowledge nothing except a little.' 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 But on account of mercy from your Lord-- surely His grace to you is abundant. 87 Say, "If all human beings and jinn were to come together to bring the equivalent of this Quran, they could not do so, even if they all were to help each other. 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 say: 'We will not believe in you until you make a spring gush from the earth for us, 90 Or there be for thee a garden of date-palms and wine, and thou causest in the midst thereof rivers to gush forth. 91 “Or you cause the sky to fall upon us in pieces like you said – or bring Allah and the angels as Witness.” 92 or thou have a house [made] of gold, or thou ascend to heaven - but nay, we would not [even] believe in thy ascension unless thou bring down to us [from heaven] a writing which we [ourselves] could read! Say thou, [O Prophet:] "Limitless in His glory is my Sustainer! Am I, then, aught but a mortal man, an apostle?" 93
