Chapter on the Testimony of the Executor for the Deceased Who Has a Debt

Muhammad ibn al-Hasan al-Saffar, may Allah سبحانه وتعالى have mercy on him, wrote to Abu Muhammad al-Hasan ibn Ali عليه السلام: "Is the testimony of the executor (al-wasi) for the deceased regarding a debt owed to him by a man acceptable along with another just witness?" Imam عليه السلام replied: "If another just witness testifies with him, then the claimant must take an oath." He also wrote to Imam عليه السلام: "Is it permissible for the executor to testify for the heir of the deceased, whether young or old, regarding a right owed to him by the deceased or by another person, especially if he is the custodian of the young heir but not the custodian of the older one?" Imam عليه السلام replied: "Yes, the executor should testify truthfully and must not conceal his testimony." Furthermore, he wrote to Imam عليه السلام: "Is the testimony of the executor against the deceased regarding a debt, along with another just witness, acceptable?" Imam عليه السلام replied: "Yes, but only after an oath."
