Musnad Ahmad 1153:132

Ibn Idris narrated to us, he said: I heard Ubayd Allah ibn Amr, and Malik ibn Anas informed us, from Talhah ibn Abd al-Malik, from al-Qasim, from Aisha, who said: The Messenger of Allah, peace and blessings of Allah be upon him, said: "Whoever vows to obey Allah, the Mighty and Majestic, let him obey Him. And whoever vows to disobey Allah, the Mighty and Majestic, let him not disobey Him."
