2. Muhammad ibn Yahya has narrated from al-Husayn ibn Ali ibn Ribat from Muhammad ibn al-Salt who has narrated the following: “I once asked abu al-Hassan, al-Rida’ (a.s.), about the case of certain friends who were on a journey when their road was blocked, and they caught the thieves, then certain ones of them testified against the others. He (the Imam) said, ‘Their testimony is not admissible unless the thieves confess or others testify against them.’”

3. Muhammad ibn Yahya has said that Muhammad ibn al-Hassan once wrote to abu Muhammad (a.s.), asking if testimony of executor of the will is acceptable for the deceased about a loan that a man owes to the deceased with one more just witness. He (the Imam) (a.s.), signed the answer that said: ‘If one more just man testifies with him then the plaintiff must take an oath.’ He also wrote asking if it is permissible for an executor of the will to testify for an heir of the deceased, small or an adult in a right for him on the deceased or on others and he is the one who takes possession for the heir who is a minor and not an adult. He (the Imam), signed the answer that said, ‘Yes, it is proper for an executor of the will to testify for a right and he must not hide a testimony.’ He wrote asking that if the testimony of an executor of the will along with the testimony of another just man is admissible against the deceased. He (the Imam) (a.s.), signed the answer that said, ‘Yes, it is acceptable with an oath.’”
