Chapter on Hunting and Slaughtering
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 36
وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: "مَنِ اُضْطُرَّ إِلَى اَلْمَيْتَةِ وَ اَلدَّمِ وَ لَحْمِ اَلْخِنْزِيرِ فَلَمْ يَأْكُلْ شَيْئاً مِنْ ذَلِكَ حَتَّى يَمُوتَ فَهُوَ كَافِرٌ"
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "Whoever is compelled by necessity to eat from a dead animal, blood, or the flesh of a pig, yet refrains from eating any of it until he dies, then he is considered a disbeliever."
