The similitude of the life of the world is only as the rain which We send down from heaven, wherewith maingleth the growth of the earth, of which men and cattle eat, until, when the earth putteth on her oranament and is adorned, and the inhabitants thereof imgine that they are potent over it, there cometh unto it Our command by night or by day, then We make it stubble as though it had not flourished yesterday. Thus We detail the signs unto a people who ponder.
