Sayyiduna Abd al-Rahman bin Mughaffal al-Sulami (may Allah be pleased with him) narrates that he asked the Prophet (peace and blessings be upon him). He says: I said: "What do you say about the hyena?" He said: "I neither eat it nor forbid it." (The narrator says:) So I say: whatever the Prophet (peace and blessings be upon him) did not forbid, I eat it. I asked: "What do you say about the rabbit?" The Prophet (peace and blessings be upon him) said: "I neither eat it nor declare it unlawful." I said: "Whatever you do not declare unlawful, I eat it." I said: "O Messenger of Allah, what do you say about the fox?" The Prophet (peace and blessings be upon him) said: "Does anyone eat that?" I said: "What do you say about the wolf?" The Prophet (peace and blessings be upon him) said: "Does anyone eat that?"
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains al-Hasan bin Abi Ja'far, whom a group of the Imams declared da'if (weak), while Ibn Adi and others declared him thiqah (trustworthy).
