Hadith 8:2700
Abu Bakr narrated to us, he said: Ghundar narrated to us, from Shu'bah, from al-Hakam, from Sa'id ibn Jubayr, that he said regarding the obligatory sacrificial animal (hady): He shall not eat from it, and he is liable for a penalty (if he does). And he said regarding the voluntary (hady): He may eat from it.
حدثنا أبو بكر قال نا غندر عن شعبة عن الحكم عن سعيد بن جبير أنه قال في الهدي الواجب لا يأكل منه وعليه جزاء وقال في التطوع يأكل منه
