Musnad Ahmad 790:140

'Affan narrated to us, 'Abd al-Warith narrated to us, Muhammad ibn al-Zubayr narrated to us, my father narrated to me, that a man narrated to him that he asked 'Imran ibn Husayn about a man who made a vow not to attend prayer in a mosque. 'Imran said: I heard the Messenger of Allah, peace and blessings of Allah be upon him, say: "There is no vow in anger, and its expiation is the expiation of an oath."
