Ali ibn Ibrahim has narrated from his father from certain persons of his people from ‘Asem ibn Humayd from Muhammad ibn Muslim who has narrated the following: “I once asked abu Ja‘far عليه السلام, about the case of a man who has testimony; if it is obligatory on him to take an oath. He (the Imam) said, ‘No, it is not obligatory on him/”
