Musnad Ahmad 5:764

Muhammad ibn Abi ‘Adi narrated to us, from Muhammad ibn Ishaq, [who said]: Aban ibn Salih narrated to me, from ‘Ikrimah, who said: I stood with al-Husayn, and I did not cease hearing him saying, "Labbayk" (Here I am, O Allah), until he threw the pebble at the Jamrah. I said, "O Abu ‘Abd Allah, what is this talbiyah?" He said, "I heard ‘Ali ibn Abi Talib, may Allah be pleased with him, reciting the talbiyah until he reached the Jamrah, and he narrated to me that the Messenger of Allah, peace and blessings of Allah be upon him, recited the talbiyah until he reached it."
