And We have placed within the heaven great stars and have beautified it for the observers. 16 We have protected them from every condemned devil, 17 Save him who stealeth the hearing, and them doth a clear flame pursue. 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 to provide you and those for whose sustenance you are not responsible, with the necessities of life. 20 With Us is the source of everything and We do not send it down except in a known quantity. 21 We send the winds fertilizing, and We send down out of heaven water, from which you drink and you are not its treasurers. 22 And verily, it is We Who give life, and Who give death: it is We Who remain inheritors (after all else passes away). 23 And We have already known the preceding [generations] among you, and We have already known the later [ones to come]. 24 Your Lord will surely gather them together: Certainly He is all-wise and all-knowing. 25
