And assuredly We have set constellations in the heaven and made it fairseeming unto the beholders 16 And We have kept it guarded from every outcast devil. 17 Except one who steals a hearing and is pursued by a clear burning flame. 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 We have made in it means of subsistence for you and for him for whom you are not the suppliers. 20 With Us is the source of everything and We do not send it down except in a known quantity. 21 We send rain-impregnated winds, and water from the sky which you drink, but you are not the keepers of its store. 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 indeed We know those among you who came forward and indeed We know those among you who remained behind. 24 and it is thy Lord shall muster them, and He is All-wise, All-knowing. 25
