Hadith #5

عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ اللَّهِ عَنْ أَبِيهِ عَنْ عَبْدِ اللَّهِ بْنِ الْفَضْلِ النَّوْفَلِيِّ عَنْ أَبِيهِ عَنْ بَعْضِ أَصْحَابِنَا عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ قُلْتُ لَهُ رُبَّمَا رَمَيْتُ بِالْمِعْرَاضِ فَأَقْتُلُ فَقَالَ إِذَا قَطَعَهُ جَدْلَيْنِ فَارْمِ بِأَصْغَرِهِمَا وَ كُلِ الْأَكْبَرَ وَ إِنِ اعْتَدَلَا فَكُلْهُمَا .

5. A number of our people have narrated from Ahmad ibn abu ‘Abd Allah from his father from ‘Abd Allah ibn al-Fadl al-Nawfaliy from his father from certain persons of our people who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about my hunting with a flareless arrow and it kills. He (the Imam) said, ‘If it is cut into two pieces then throw away the smaller piece and use the larger one for food. If both are equal then use both.’”
