A merchant, having suffered loss of a thousand dinars, enjoined his son not to reveal it to anyone. The boy said: `It is thy order and I shall not tell it but thou must inform me of the utility of this proceeding and of the propriety of concealment.? He replied: `For fear the misfortune would be double; namely, the loss of the money and, secondly, the joy of neighbours at our loss.?

 Reveal not thy grief to enemies 
 Because they will say `La haul? but rejoice.
