They question you about the Spirit. Say, "The Spirit is at my Lord's command, and you have been granted but little knowledge." 85 If We pleased We could take away that which We have revealed to you then you should find none to guard you against Us, 86 excepting by some mercy of thy Lord; surly His favour to thee is great. 87 Say: "If the mankind and the jinns were together to produce the like of this Quran, they could not produce the like thereof, even if they helped one another." 88 And We have certainly diversified for the people in this Qur'an from every [kind] of example, but most of the people refused [anything] except disbelief. 89 They say, 'We will not believe thee till thou makest a spring to gush forth from the earth for us, 90 or that there be a garden of palms and vines for you and then you cause rivers to abundantly flow forth through them; 91 Or, let chunks of sky fall over us, as you assert (you will); or, bring God and the angels as a surety; 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
