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 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 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 the treasures of it, and We do not send it down but in a known measure. 21 We send impregnating winds and send down water from the sky for you to drink and you have no (control over its) storage. 22 And verily We! it is We who give life and death, and We shall be the survivors. 23 We surely know those of you who go forward and those of you who lag behind. 24 And verily thy Lord! He will gather them, and verily He is Wise, Knowing. 25
