Musnad Ahmad 1153:1859

Ibn Numayr narrated to us, he said: Yahya bin Sa’id narrated to us, from Talhah bin ‘Abd al-Malik, from al-Qasim bin Muhammad, from ‘Aishah, who said: The Messenger of Allah (may Allah bless him and grant him peace) 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."
