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)

except for Mercy from your Lord; for His favor to you is great indeed. (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)

Indeed, We have set forth for mankind in this Koran every kind of parable, yet most people refuse all except disbelief. (89)

They say: 'We will not believe in you until you make a spring gush from the earth for us, (90)

or, until you own a garden of palms and vines and cause rivers to gush forth with abundant water in them; (91)

or, until you cause the sky to fall upon us in pieces, as you have claimed, or, as a surety bring Allah with the angels in front; (92)

or, until you possess an ornate house of gold, or ascend into the heavens; and we will not believe in your ascension until you have brought down for us a book which we can read. ' Say: 'Exaltations to my Lord! Am I anything except a human Messenger? ' (93)

Nothing prevented people from believing when guidance came to them but (the excuse): 'Has Allah sent a human as a Messenger? ' (94)

Say: 'Had there been angels walking at peace in the earth, We would have sent down an angel from heaven to them as a Messenger. ' (95)
