Musnad Ahmad 764:1

Zayd ibn al-Hubab narrated to us, Usamah ibn Zayd narrated to us, he said: Al-Zuhri narrated to me, from Abd al-Rahman ibn Azhar, who said: "I saw the Messenger of Allah, may Allah bless him and grant him peace, weaving through the people on the day of Hunayn, asking about the encampment of Khalid ibn al-Walid. Then a drunk man was brought to him, and he ordered those who were with him to strike him with what was in their hands."
