The parable of the life of this world is that of water which We send down from the sky. It mingles with the earth’s vegetation from which humans and cattle eat. When the earth puts on its luster and is adorned, and its inhabitants think they have power over it, Our edict comes to it, by night or day, whereat We turn it into a mown field, as if it did not flourish the day before. Thus do We elaborate the signs for a people who reflect.
