Musnad Abu Ya'la al-Mawsili 150:279

Abbad ibn Musa narrated to us, Ibn al-Mubarak narrated to us, Yunus informed me, from al-Zuhri, from Abu Salamah, from Aisha, from the Prophet (peace be upon him), who said: "There is no fulfillment for a vow in disobedience to Allah, and its expiation is the expiation of an oath."
