عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عُمَرَ بْنِ أُذَيْنَةَ عَنِ الْفُضَيْلِ بْنِ يَسَارٍ قَالَ سَأَلْتُ أَبَا جَعْفَرٍ ( عليه السلام ) عَنْ رَجُلٍ ذَبَحَ فَسَبَقَهُ السِّكِّينُ فَقَطَعَ رَأْسَهُ فَقَالَ هُوَ ذَكَاةٌ وَحِيَّةٌ لَا بَأْسَ بِهِ وَ بِأَكْلِهِ .
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Umar ibn ‘Udhaynah from al-Fudayl ibn Yasar who has said the following: “I once asked abu Ja‘far , about the case of a man who slaughters an animal but by mistake the knife cuts off its head before it dies. He (the Imam) said, ‘It is a fast slaughtering and it is not unlawful to use it for food.’”
