Musnad Ahmad 32:2162

Bahz narrated to us, Hammad narrated to us, Hisham ibn Zayd narrated to us, from his grandfather Anas ibn Malik, who said: "I was a young boy, a good hunter, so I hunted a rabbit and we roasted it. Abu Talha sent me with its hindquarters to the Messenger of Allah, may Allah bless him and grant him peace, and I brought it to him."
