We have set in heaven constellations and decked them out fair to the beholders, 16 And We guard it against every accursed Shaitan, 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 and provided thereon means of livelihood for you [O men] as well as for all [living beings] whose sustenance does not depend on you. 20 With Us is the source of everything and We do not send it down except in a known quantity. 21 We send fertilizing winds, and then cause rain to descend from the sky, providing you abundant water to drink even though you could not have stored it up for yourselves. 22 Truly, it is We who bring to life and We who cause death and We are the inheritor of all things. 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 and it is thy Lord shall muster them, and He is All-wise, All-knowing. 25
