And they ask thee regarding the spirit; say thou: the spirit is by the command of my Lord, and ye have not been vouchsafed of knowledge save a little. 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 Except as a Mercy from your Lord. Verily! His Grace unto you (O Muhammad SAW) is ever great. 87 Say: "Surely, if mankind and jinn were to get together to produce the like of this Qur'an, they will never be able to produce the like of it, howsoever they might help one another." 88 We have given examples of every kind to men in this Qur'an in various ways, and even then most men disdain everything but unbelief, 89 and so they say: "[O Muhammad,] we shall not believe thee till thou cause a spring to gush forth for us from the earth, 90 Or [until] you have a garden of palm tress and grapes and make rivers gush forth within them in force [and abundance] 91 or till thou makest heaven to fall, as thou assertest, on us in fragments, or thou bringest God and the angels as a surety, 92 “Or you have a house of gold, or you ascend up into heaven; and even then we shall not believe in your ascent unless you send down a book upon us, which we may read”; say (O dear Prophet Mohammed – peace and blessings be upon him), “Purity is to my Lord – who am I except a human, sent by Allah?” (* These can be done, only when Allah commands.) 93
