The life of the world is like the water which We send down from the sky, and which is absorbed by the plants of the earth, from which men and cattle eat. But when the earth has taken on its finest appearance, and looks beautiful, and its people think they have it under their control, then by day or by night, Our command comes to it and We convert it into a field of stubble, as if nothing had existed there the day before. Thus We make plain Our revelations for those who reflect.
