Musnad Ahmad 22:8

'Affan narrated to us, Wuhayb narrated to us, 'Abdullah ibn 'Uthman ibn Khuthaym narrated to us, from Abu al-Tufayl, from al-Fadl ibn 'Abbas, that he was the rider behind the Prophet, may Allah bless him and grant him peace, from Muzdalifah to Mina. He did not cease reciting the talbiyah until he threw the pebbles at the Jamrah.
