"I said: 'O Messenger of Allah, I release my dog and he catches the game, but I cannot find anything with which to slaughter it, so I slaughter it with a sharp-edged stone or a stick.' He said: 'Shed the blood with whatever you want, and mention the name of Allah."" (Using translation from Nasāʾī 4304)
عَنْ عَدِيِّ بْنِ حَاتِمٍ قُلْتُ يَا رَسُولَ اللهِ إِنِّي أُرْسِلُ كَلْبِي فَيَأْخُذُ الصَّيْدَ فَلَا أَجِدُ مَا أَذْبَحُهُ بِهِ فَأَذْبَحُهُ بِالْمَرْوَةِ وَالْعَصَا؟ قَالَ «أَهْرِقِ الدَّمَ بِمَا شِئْتَ وَاذْكُرِ اسْمَ اللهِ»
