6. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from abu Isma’il al-Basri from Fudayl ibn Yasar who has said the following: “Once Abu ‘Abdillah (a.s.) said to me, ‘O Fudayl, the truthfulness of a truthful person is first verified by Allah, the Most Majestic, the Most Holy. He knows that he is truthful. Then his own soul confirms; it knows his truthfulness.’”
