And We have placed within the heaven great stars and have beautified it for the observers. 16 And We have guarded it from every outcast 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 out (like a carpet); set thereon mountains firm and immovable; and produced therein all kinds of things in due balance. 19 And We have provided therein means of subsistence,- for you and for those for whose sustenance ye are not responsible. 20 And there is not a thing but with Us are its treasuries, and We do not send it down except in a known measure. 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 And certainly We! We it is Who give life, and cause death, and We are the Inheritors. 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
