[Machine] He said, "O Messenger of Allah, write for me a piece of land." He said, "How can I write it when it is in enemy territory?" So the Messenger of Allah said, "By the One who sent you with the truth, you will possess whatever is beneath their feet." The Messenger of Allah was amazed by that, so he looked at his companions and wrote it for him. Then he said, "O Messenger of Allah, we are in a hunting land, so what is permissible for us to eat of what is forbidden to us?" He said, "If you send your trained or domesticated dog and you mention the name of Allah and it catches and kills, then eat. And if you send your dog that is not trained, then you do not know what it caught, so do not eat. And whatever your arrow brings back to you, then eat."  

أَنَّهُ قَالَ يَا رَسُولَ اللهِ اكْتُبْ لِي بِأَرْضٍ قَالَ «كَيْفَ أَكْتُبُ وَهِي بِأَرْضِ الْحَرْبِ» فَقَالَ وَالَّذِي بَعَثَكَ بِالْحَقِّ لَيَمْلُكَنَّ مَا تَحْتَ أَقْدَامِهِمْ فَأَعْجَبَ رَسُولَ اللهِ ﷺ ذَلِكَ فَنَظَرَ إِلَى أَصْحَابِهِ فَكَتَبَ لَهُ رَسُولُ اللهِ ﷺ ثُمَّ قَالَ يَا رَسُولَ اللهِ إِنَّا بِأَرْضِ صَيْدٍ فَمَا يَحِلُّ لَنَا مِمَّا يَحْرُمُ عَلَيْنَا؟ فَقَالَ «إِذَا أَرْسَلْتَ كَلْبَكَ الْمُعَلَّمَ أَو الْمُكَلَّبَ وَذَكَرْتَ اللهَ وَأَخَذَ وَقَتَلَ فَكُلْ وَإِذَا أَرْسَلْتَ كَلْبَكَ الَّذِي لَيْسَ بِمُعَلَّمٍ فَمَا أَدْرَكْتَ ذَكَاتَهُ فَكُلْ وَمَا لَمْ تُدْرِكْ فَلَا تَأْكُلْ وَمَا رَدَّ عَلَيْكَ سَهْمُكَ فَكُلْ»
