57.20 . Know that the life of this world is only play , and idle talk , and pageantry , and boasting among you , and rivalry in respect of wealth and children ; as the likeness of vegetation after rain , whereof the growth is pleasing to the husbandman , but afterward it drieth up and thou seest it turning yellow then it becometh straw . And in the Hereafter there is grievous punishment , and ( also ) forgiveness from Allah and His good pleasure , whereas the life of the world is but matter of illusion .
