وَعَنْهُ قَالَ: قُلْتُ: يَا رَسُولَ اللَّهِ إِنَّا نُرْسِلُ الْكِلَابَ الْمُعَلَّمَةَ قَالَ: «كُلْ مَا أَمْسَكْنَ عَلَيْكَ» قُلْتُ: وَإِنْ قَتَلْنَ؟ قَالَ: «وَإِنْ قَتَلْنَ» قُلْتُ: إِنَّا نَرْمِي بِالْمِعْرَاضِ. قَالَ: «كُلُّ مَا خزق وَمَا أصَاب بعرضه فَقتله فَإِنَّهُ وقيذ فَلَا تَأْكُل»
English Translation
He said he told God’s messenger that he set off trained dogs, and he replied, “Eat what they catch for you.” He asked if that applied even if they killed the game, and he replied that it did. He told him that he shot featherless arrows (mi'rad)* and he replied, “Eat what they pierce, but what they strike with the middle part and kill is beaten to death, so do not eat it.” *The mi'rad was thick in the middle and slender at the ends. It was liable to strike the animal with its middle part. (Bukhari and Muslim.)
