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 Had We wanted, We could have removed the Spirit through whom We sent you revelation. Then you would not have found anyone to intercede with Us for you 86 Unless your Lord have mercy. His blessings on you are great indeed. 87 Say: "If all mankind and all invisible beings would come together with a view to producing the like of this Qur'an, they could not produce its like even though they were to exert all their strength in aiding 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 And they say: "We shall not believe in you (O Muhammad SAW), until you cause a spring to gush forth from the earth for us; 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 thou causest the heaven to fall upon us, as thou assertest, in pieces, or thou bringest God and the angels face to face. 92 or that there come to be for you a house of gold, or that you ascend to the sky - though we shall not believe in your ascension (to the sky) - until you bring down a book for us that we can read." Say to them, (O Muhammad): "Holy is my Lord! Am I anything else than a human being, who bears a Message (from Allah)?" 93
