It is narrated from Muhammad bin Safwan (may Allah be pleased with him) that he caught two rabbits but found no knife or iron implement with which to slaughter them, so he slaughtered them with a sharp-edged stone. Then he came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah (peace and blessings be upon him), I hunted two rabbits but found no iron with which to slaughter them, so I slaughtered them with a marwah (sharp stone). May I eat them?" He (peace and blessings be upon him) said: "Yes, eat them." This hadith is sahih (authentic) on the condition of Imam Muslim, although there is a disagreement over its narration from Imam al-Sha'bi, and the two Shaykhs (Bukhari and Muslim) did not record it.
