From Sahih Bukhari (Hadith 5499):
Narrated `Abdullah:Allah's Messenger (ﷺ) said that he met Zaid bin `Amr Nufail at a place near Baldah and this had happened before Allah's Messenger (ﷺ) received the Divine Inspiration. Allah's Messenger (ﷺ) presented a dish of meat (that had been offered to him by the pagans) to Zaid bin `Amr, but Zaid refused to eat of it and then said (to the pagans), "I do not eat of what you slaughter on your stonealtars (Ansabs) nor do I eat except that on which Allah's Name has been mentioned on slaughtering
