مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ عَنِ الْعَلَاءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ ( عليه السلام ) قَالَ سَأَلْتُهُ عَنِ الذَّبِيحَةِ فَقَالَ ( عليه السلام ) اسْتَقْبِلْ بِذَبِيحَتِكَ الْقِبْلَةَ وَ لَا تَنْخَعْهَا حَتَّى تَمُوتَ وَ لَا تَأْكُلْ مِنْ ذَبِيحَةٍ مَا لَمْ تُذْبَحْ مِنْ مَذْبَحِهَا .
5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Hassan ibn Mahbub from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “I once asked abu Ja‘far , about slaughtering. He (the Imam) said, ‘You must turn the animal to be slaughtered toward al-Qiblah (al-Ka‘bah) and do not cut its spinal cord before it dies. You must not use for food what is not properly slaughtered from the proper place.’”
