1. Muhammad ibn Yahya has narrated the following: “Muhammad ibn al-Hassan once wrote to abu Muhammad (a.s.), about the case of a man who dies and appoints two people as executors of his will, if it is permissible for one of them to deal with one-half of the legacy and the other with the other half of the legacy. He (the Imam) signed the answer that said, ‘
It is not suitable for them to oppose the deceased. They must work as they are instructed, by the will of Allah.’”
