When Cassim came home, his wife said to him: "Cassim, I know you think yourself rich, but you are much mistaken; Ali Baba is infinitely richer than you; he does not count his money, but measures it." Cassim desired her to explain the riddle, which she did, by telling him the stratagem she had used to make the discovery, and showed him the piece of money, which was so old that they could not tell in what prince's reign it was coined. Cassim, instead of being pleased, conceived a base envy at his brother's prosperity; he could not sleep all that night, and went to him in the morning before sunrise, although after he had married the rich widow, he had never treated him as a brother, but neglected him. "Ali Baba," said he, accosting him, "you are very reserved in your affairs; you pretend to be miserably poor, and yet you measure gold." "How, brother?" replied Ali Baba; "I do not know what you mean: explain yourself." "Do not pretend ignorance," replied Cassim, showing him the piece of gold his wife had given him. "How many of these pieces," added he, "have you? My wife found this at the bottom of the measure you borrowed yesterday."
