We have set constellations in the heavens and made them pleasing to the beholders, 16 and We have guarded it from every accursed 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 have spread it and cast therein firmly set mountains and caused to grow therein [something] of every well-balanced thing. 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 And We send the fecundating winds, then cause the rain to descend from the sky, therewith providing you with water (in abundance), though ye are not the guardians of its stores. 22 It is We who give life and We who give death, and We are the One who will abide. 23 We surely know those of you who go forward and those of you who lag behind. 24 Indeed your Lord will gather them all together. Surely He is All-Wise, All-Knowing. 25
