Musnad Ahmad 22:41

Kathir ibn Hisham informed us, he said: Furat narrated to us, Abd al-Karim narrated to us, from Sa'id ibn Jubayr, from Ibn Abbas, from al-Fadl ibn Abbas: "That he was the rider behind the Messenger of Allah, may Allah bless him and grant him peace, and he did not cease to recite the talbiyah until he threw the Jamrat al-Aqabah."
