My father narrated to us. He said: Sa`d b. `Abdullah narrated to us from Ibrahim b. Hashim from `Ubaydullah b. `Abdullah al-Dahqan from Darast b. Abi Mansur from `Abdullah b. Sinan. He said: Abu `Abdillah al-Sadiq said:

Do not jest, or your light will dissipate. Do not lie, or your splendour will dissipate. Beware of two traits: (1) restlessness, and (2) laziness. If you are restless, you will not be able to bear a responsibility patiently; and if you are lazy, you will not be able to fulfill the right [of another]. He said: The Messiah would say: He whose worries multiply, his body becomes ill. He who worsens his character, his soul suffers. He whose speech multiplies, his errors multiply. He whose lying multiplies, his splendour dissipates. He who disputes men excessively, his chivalry dissipates.
