عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ بَعْضِ أَصْحَابِهِ قَالَ
سَأَلْتُ أَبَا عَبْدِ اللَّهِ ( عليه السلام ) عَنْ ذَبِيحَةِ أَهْلِ الْكِتَابِ قَالَ فَقَالَ وَ اللَّهِ مَا يَأْكُلُونَ ذَبَائِحَكُمْ فَكَيْفَ تَسْتَحِلُّونَ أَنْ تَأْكُلُوا ذَبَائِحَهُمْ إِنَّمَا هُوَ الِاسْمُ وَ لَا يُؤْمَنُ عَلَيْهَا إِلَّا مُسْلِمٌ .
16. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from certain persons of his people who has said the following:
“I once asked abu ‘Abd Allah 
, about the animals the people of the book slaughter. He (the Imam) said, ‘By Allah they do not eat what you slaughter; then how can you consider what they slaughter as lawful? It is a matter of name (mentioning the name of Allah), and no one can be trusted in it except a Muslim.’”
