Musnad Ahmad 1153:1175

Yahya ibn Ishaq narrated to us, Abu 'Awanah informed us, from 'Umar ibn Abi Salamah, from his father, from 'Aishah, she said: When the verse of choice (al-khiyar) was revealed, the Messenger of Allah, peace and blessings of Allah be upon him, called me and said: "O 'Aishah, I wish to mention a matter to you, so do not decide anything regarding it until you consult your parents." She said: "What is it?" She said: Then the Messenger of Allah, peace and blessings of Allah be upon him, called me and recited this verse to me: {O Prophet, say to your wives} [Al-Ahzab: 28] {if you desire Allah and His Messenger and the Home of the Hereafter} [Al-Ahzab: 29]—the entire verse. She said: So I said: "I have chosen Allah and His Messenger." She said: The Messenger of Allah, peace and blessings of Allah be upon him, rejoiced at that.
