It was narrated from Muhammad bin Safwan that:
he caught two rabbits and he could not find a knife with which to slaughter then, so he slaughtered them with Marwah. Then he came to the Prophet and said: "O Mesenger of Allah! I caught two rabbits but I could not find a knife with which to slaughter them, so I slaughtered them with Marwah;l can I eat them?" He said: "Eat (them)."
