“I said: ‘O Messenger of Allah, we hunt game but we cannot find anything but the sharp edge of a stone or stick (with which to slaughter it).’ He said: ‘Cause the blood to flow with whatever you want, and mention the Name of Allah over it.’” (Using translation from Ibn Mājah 3177)
قُلْتُ يَا رَسُولَ اللهِ إِنَّا نَصِيدُ الصَّيْدَ فَلَا نَجِدُ سِكِّينًا إِلَّا الظِّرَارَ وَشِقَّةَ الْعَصَا فَقَالَ رَسُولُ اللهِ ﷺ أَمَرَّ الدَّمَ بِمَا شِئْتَ وَاذْكُرْ اسْمَاللهِ
