Musnad Ahmad 27:920

'Affan narrated to us, Wuhayb narrated to us, Musa ibn 'Uqbah narrated to us, Salim informed me that he heard 'Abdullah narrating from the Messenger of Allah (may Allah bless him and grant him peace): That he met Zayd ibn 'Amr ibn Nufayl at the lower part of Baldah, and that was before the revelation had descended upon the Messenger of Allah (may Allah bless him and grant him peace). The Messenger of Allah (may Allah bless him and grant him peace) presented to him a tray containing meat, but he refused to eat from it. Then he said: "I do not eat from what you slaughter upon your altars, and I do not eat except from that upon which the name of Allah has been mentioned." 'Abdullah ibn 'Umar narrated this from the Messenger of Allah (may Allah bless him and grant him peace).
