'Adi b. Hatim reported:
حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ ، أَخْبَرَنَا عَاصِمٌ ، عَنِ الشَّعْبِيِّ ، عَنْ عَدِيِّ بْنِ حَاتِمٍ ، قَالَ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنِ الصَّيْدِ قَالَ " إِذَا رَمَيْتَ سَهْمَكَ فَاذْكُرِ اسْمَ اللَّهِ فَإِنْ وَجَدْتَهُ قَدْ قَتَلَ فَكُلْ إِلاَّ أَنْ تَجِدَهُ قَدْ وَقَعَ فِي مَاءٍ فَإِنَّكَ لاَ تَدْرِي الْمَاءُ قَتَلَهُ أَوْ سَهْمُكَ " .
I asked Allah's Messenger (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.
