Hadith #7

مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ يَحْيَى عَنْ غِيَاثِ بْنِ إِبْرَاهِيمَ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) فِي الرَّجُلِ يَضْرِبُ الصَّيْدَ فَيَقُدُّهُ نِصْفَيْنِ قَالَ يَأْكُلُهُمَا جَمِيعاً فَإِنْ ضَرَبَهُ وَ أَبَانَ مِنْهُ عُضْواً لَمْ يَأْكُلْ مِنْهُ مَا أَبَانَ [مِنْهُ] وَ أَكَلَ سَائِرَهُ .

7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn Yahya from Ghiyath ibn Ibrahim who has said the following: “About the case of a man who hunts a prey and cuts it into two pieces, abu ‘Abd Allah, ‘Alayhi al- Salam, has said, ‘He can use both of them for food but if he cuts a part only he then must not eat what is cut off but he can eat the rest.’”
