It is narrated from Imam al-Hasan al-Basri (may Allah have mercy on him) that he said: "If there could have been anyone wholly unacquainted with lying (that is, in whose life and conduct no trace of a lie was found), it was certainly Sayyiduna Umar (may Allah be pleased with him)."
Its chain is jayyid (good), and Imam Musaddad bin Musarhad narrated it in his Musnad.
