The metaphor of the life of this world is that of water which We send down from the sky, and which then mingles with the plants of the earth to provide food for both people and animals. Then, when the earth is at its loveliest and takes on its fairest guise and its people think they have it under their control, Our command comes upon it by night or day and We reduce it to dried-out stubble, as though it had not been flourishing just the day before! In this way We make Our Signs clear for people who reflect.
