And He subjected for you the night for your rest, and the day for your living, and He subjected for you the sun as a radiance, and the moon as a light and for the knowledge of the years and the reckoning, and other than that of the benefits, and the stars in the heaven are subjected for you by the command of Allah for the knowledge of the times, and the ripening of the fruits and crops, and the being guided by them in the darknesses. Indeed in that subjection are surely clear signs for a people who will understand from Allah His arguments and His proofs.
