It is We Who have divided the heavens into many fortified spheres8 for the sake of administration and adorned and decked them out fair to the beholders,9 and guarded them from every accursed Satan.10 No Satan can pass through them except that an eaves-dropper might hear something,11 but a fiery flame pursues that eaves-dropper.12 We stretched forth the Earth, and set mountains firmly upon it, and caused to grow therein every kind of vegetable in balanced measure.13 And We provided therein means of sustenance for you and for many other creatures for whom you do not provide. There is not a thing whose treasures are not with Us, and We send down each thing in appropriate measure.14 It is We Who send the fertilizing winds: then We send down' water from heaven, and then We give it to you to drink; and it is not you who hold the store of this wealth. It is We Who give life and death and We will be the inheritors of all.15 We have full knowledge about those who lived before you, and We are keeping watch over their successors. Most surely your Lord will gather them together for He is All-Wise, All-Knowing.16
