We have placed constellations in heaven and have beautified it for beholders, 16 And We have protected it from every devil expelled [from the mercy of Allah] 17 save him who may eavesdrop, and then a bright flame pursues him. 18 And the earth - We have spread it out wide, and placed on it mountains firm, and caused [life] of every kind to grow on it in a balanced manner, 19 We have provided on it sustenance for you, and for those you cannot provide. 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 And verily We! it is We who give life and death, and We shall be the survivors. 23 And indeed, We know the first generations of you who had passed away, and indeed, We know the present generations of you (mankind), and also those who will come afterwards. 24 And indeed, your Lord will gather them; indeed, He is Wise and Knowing. 25
