مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ عَنْ أَبِي بَصِيرٍ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) إِذَا أَرْسَلْتَ بَازاً أَوْ صَقْراً أَوْ عُقَاباً فَلَا تَأْكُلْ حَتَّى تُدْرِكَهُ فَتُذَكِّيَهُ وَ إِنْ قَتَلَ فَلَا تَأْكُلْ .

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Ali ibn abu Hamzah from abu Basir who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said, ‘If you send a falcon, a hawk or an eagle to catch a prey, do not use it for food unless you arrive in time to slaughter it properly, and if it has already killed the prey then do not use it for food.’”
