We have placed constellations in heaven and have beautified it for beholders, 16 and We have guarded it from every accursed devil: 17 excepting such as listens by stealth -- and he is pursued by a manifest flame. 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 and there appointed for you is a livelihood, and for those you do not provide. 20 With Us is the source of everything and We do not send it down except in a known quantity. 21 And We have sent the fertilizing winds and sent down water from the sky and given you drink from it. And you are not its retainers. 22 Lo! and it is We, even We, Who quicken and give death, and We are the Inheritor. 23 And well do We know [the hearts and deeds of all human beings - both] those who lived before you and those who will come after you; 24 Assuredly it is thy Lord Who will gather them together: for He is perfect in Wisdom and Knowledge. 25
