(2) Even as those before you who were mightier than you in strength, and more affluent than you in wealth and children. They enjoyed their lot awhile, so ye enjoy your lot awhile even as those before you did enjoy their lot awhile. And ye prate even as they prated. Such are they whose works have perished in the world and the Hereafter. Such are they who are the losers.
