Musnad Abu Ya'la al-Mawsili 150:170

Narrated to us Muhriz ibn 'Awn, narrated to us Hassan ibn Ibrahim, from Yunus ibn Yazid, from al-Zuhri: 'Urwah ibn al-Zubayr informed me that 'Aishah, the wife of the Prophet, may Allah bless him and grant him peace, informed him that the Messenger of Allah, may Allah bless him and grant him peace, passed away while he was sixty-three years old. He said: And Ibn al-Musayyib informed me of that.
