Musnad Ahmad 32:1856

Ibrahim ibn Ishaq al-Taliqani narrated to us, Ibn al-Mubarak narrated to us, from al-Awza'i, from Ishaq ibn Abi Talhah, from Anas ibn Malik, who said: "Abu Talhah used to shield himself with the Prophet, may Allah bless him and grant him peace, behind a single shield. Abu Talhah was an excellent archer. Whenever he would shoot, the Prophet, may Allah bless him and grant him peace, would lean forward to look at where his arrows landed."
