I asked Messenger of Allah ﷺ about hunting. He said: When you shoot your arrow, recite the name of Allah, and if you find it (the arrow) killed (that). then eat, except when you find it fallen into water, for in that case you do not know whether it is water that caused its death or your arrow. (Using translation from Muslim 1929k)   

سَأَلْتُ رَسُولَ اللهِ ﷺ عَنِ الصَّيْدِ قَالَ إِذَا رَمَيْتَ سَهْمَكَ فَاذْكُرِ اسْمَ اللهِ فَإِنْ وَجَدْتَهُ قَدْ قَتَلَ فَكُلْ وَإِنْ وَجَدْتَهُ قَدْ وَقَعَ فِي الْمَاءِ فَمَاتَ فَإِنَّكَ لَا تَدْرِي الْمَاءُ قَتَلَهُ أَوْ سَهْمُكَ فَلَا تَأْكُلْ  

[Machine] Abdullah said, "If one of you throws a hunting tool and it falls from a mountain and it dies, then do not eat it, for I fear that the fall may have caused its death. Or if it falls into water and it dies, then do not eat it, for I fear that the water may have caused its death."  

قَالَ عَبْدُ اللهِ إِذَا رَمَى أَحَدُكُمْ صَيْدًا فَتَرَدَّى مِنْ جَبَلٍ فَمَاتَ فَلَا تَأْكُلُوا فَإِنِّي أَخَافُ أَنْ يَكُونَ التَّرَدِّي قَتَلَهُ أَوْ وَقَعَ فِي مَاءٍ فَمَاتَ فَلَا تَأْكُلْهُ فَإِنِّي أَخَافُ أَنْ يَكُونَ الْمَاءُ قَتَلَهُ
