عَنْ مُحَمَّدِ بْنِ صَفْوَانَ رَضِيَ اللَّهُ عَنْهُ أَنَّهُ صَادَ أَرْنَبَيْنِ فَلَمْ يَجِدْ حَدِيدَةً يَذْبَحُهُمَا بِهَا فَذَبَحَهُمَا بِمَرْوَةٍ فَأَتَى رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَأَمَرَهُ بِأَكْلِهِمَا
It is narrated from Sayyiduna Muhammad bin Safwan that he caught two rabbits while hunting. There was nothing made of iron present with which to slaughter them, so he slaughtered them with the tip of a stone. When he came to the Noble Prophet (peace and blessings be upon him), he (peace and blessings be upon him) instructed him to eat them.
