`Ali b. Ahmad b. `Abdullah b. Ahmad b. Abi `Abdillah al-Barqi narrated to us. He said: My father narrated to us from his grandfather Ahmad b. Abi `Abdillah from Muhammad b. `Ali al-Kufi from Abi `Abdillah al-Khayyat from `Abdullah b. al-Qasim from `Abdullah b. Sinan from Abi `Abdillah al-Sadiq . He said:

Among that which Allah revealed to Musa b. `Imran is: Be [like] a worn-out robe, pure of heart, reclusive in your house, and a lantern in the night, and you will be known to the people of heaven and hidden from the people of Earth. O Musa! Beware of being insistent, and do not be of those who walk without purpose, and do not laugh without astonishment. Weep over your mistakes, O son of `Imran.
