Musannaf Ibn Abi Shayba 9:1741

Yazid ibn Harun narrated to us, from Muhammad ibn Ishaq, from Yahya ibn 'Abbad, from 'Abdullah ibn al-Zubayr, from his father, from 'Aisha, who said: I heard the Messenger of Allah, may Allah bless him and grant him peace, say: "The adulterer does not commit adultery while he is a believer."
