4. A number of our people have narrated from Sahl ibn Ziyad from Ahmad ibn abu Nasr from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has said the following
“I once asked abu Ja‘far (a.s.), if animal slaughtered by the Christian Arabs can be used for food. He (the Imam) said, ‘Ali ibn al-Husayn (a.s.), would prohibit using what they slaughtered for food, as well as their hunting and marriage with them.’”
