Imran bin Husayn (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "There is no vow in disobedience, and its expiation is the expiation of an oath."
(b) Sufyan narrates with his chain: "There is no vow in disobedience or in anger, and its expiation is like the expiation of an oath."
This too is munqati' (broken); no hearing of al-Hasan from Imran is established through a sound route.
