One evening Sultan Mahmud saw a poor man sifting dust in search of some trinkets. Mahmud thereupon threw his diamond wristlet in the heap of dust that the man had collected. Next evening he went to the same place and saw the same man engaged in the same occupation.

“What you obtained yesterday,” said the king, who was greatly astonished at the cupidity of the man, “was enough for your maintenance for ten lives, and yet you are grovelling in the dust to-day. Go and enjoy yourself.”

“The hidden treasure that I found yesterday,” replied the man, “was received from this dust. When fortune smiled on me for knocking at this door, it behoves me that I should devote myself to this work as long as I live.”
