Musannaf Ibn Abi Shayba 11:6

Abu Bakr narrated to us, he said: Ali bin Mushir narrated to us, from al-Shaybani, from al-Walid bin al-Ayzar, from Sa’d bin Iyas Abu Amr al-Shaybani, from Abdullah, who said: I asked the Prophet, peace and blessings of Allah be upon him, "Which deed is best?" He said, "Prayer at its time." I said, "Then what?" He said, "Kindness to parents." I said, "Then what?" He said, "Jihad in the way of Allah."
