Imran bin 'Uyaynah عمران بن عيينة · Sacrifice (Kitab Al-Dahaya)

explaining the verse "But the evil ones ever inspire their friend to contend with you" They used to say: Do not eat which Allah killed, but eat which you slaughtered. So Allah revealed the verse: "Eat not of (meats) on which Allah's name hath not been pronounced"...to the end of the verse.
