Musnad Ahmad 1007:74

'Abd al-Razzaq narrated to us, Ma'mar informed us, from Yahya ibn Abi Kathir, from 'Abdullah ibn Abi Qatadah, from his father, who said: I went out with the Messenger of Allah, peace and blessings of Allah be upon him, at the time of al-Hudaybiyah. My companions entered into ihram, but I did not enter into ihram. I saw a wild donkey, so I attacked it and hunted it. I mentioned its matter to the Messenger of Allah, peace and blessings of Allah be upon him, and I mentioned that I had not entered into ihram, and that I had only hunted it for him. The Prophet, peace and blessings of Allah be upon him, commanded his companions, so they ate, but he did not eat from it when I informed him that I had hunted it for him.
