it was narrated from Muhammad bin Safwan that he passed by the Prophet ﷺ with two rabbits hanging down. He said:
“O Messenger of Allah, I caught these two rabbits but I cannot find any iron* with which to slaughter them with Marwah** and eat them?” He said: “Eat.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَنْبَأَنَا دَاوُدُ بْنُ أَبِي هِنْدٍ، عَنِ الشَّعْبِيِّ، عَنْ مُحَمَّدِ بْنِ صَفْوَانَ، أَنَّهُ مَرَّ عَلَى النَّبِيِّ ﷺ بِأَرْنَبَيْنِ مُعَلِّقَهُمَا فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي أَصَبْتُ هَذَيْنِ الأَرْنَبَيْنِ فَلَمْ أَجِدْ حَدِيدَةً أُذَكِّيهِمَا بِهَا فَذَكَّيْتُهُمَا بِمَرْوَةٍ أَفَآكُلُ قَالَ " كُلْ " .
