And certainly We have made strongholds in the heaven and We have made it fair seeming to the beholders. 16 We have protected them from every condemned devil, 17 so that anyone who seeks to learn [the unknowable] by stealth is pursued by a flame clear to see. 18 And the earth -- We stretched it forth, and cast on it firm mountains, and We caused to grow therein of every thing justly weighed, 19 We have provided on it sustenance for you, and for those you cannot provide. 20 And there is not a thing but with Us are the treasures of it, and We do not send it down but in a known measure. 21 And We let loose the winds to fertilize [plants] and We send down water from the skies and let you drink thereof: and it is not you who dispose of its source 22 Truly, it is We who bring to life and We who cause death and We are the inheritor of all things. 23 And indeed We know those among you who came forward and indeed We know those among you who remained behind. 24 Your Lord will surely gather them together: Certainly He is all-wise and all-knowing. 25
