We have set in heaven constellations and decked them out fair 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 We spread out the earth, and placed mountains as anchors in it, and in it grew all things by a proper measure. 19 And created livelihoods for you in it, and created those for whom you do not provide the sustenance. 20 And there is not a thing but its (sources and) treasures (inexhaustible) are with Us; but We only send down thereof in due and ascertainable measures. 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 And verily We! it is We who give life and death, and We shall be the survivors. 23 We know the ones of you who press forward, and We know the laggards; 24 And verily, your Lord will gather them together. Truly, He is All-Wise, All-Knowing. 25
