H 38 - Narrated to me Hannan bin Sudair from Ismail [bin Ziyad] Bazzaz that he said: Imam Ja’far Sadiq said: The master of this affair is the executor of the will, while he is twenty years old. After that Ismail said: No one became the executor of the will of Imam Ja’far Sadiq who was younger; and Imam Kadhim was of the age, which Imam Ja’far Sadiq had mentioned.
