Sayyiduna Abu Umamah (may Allah be pleased with him) narrates: We set out with the Prophet (peace and blessings be upon him) to take part in a military expedition. He ordered a caller, and he announced: "Paradise is not lawful for a disobedient person. Beware! Domestic donkeys are unlawful, and every animal with fangs (the narrator is unsure, perhaps the words are:) with claws is unlawful." In one narration the wording is: "Every predator that has claws or fangs."
Al-Tabarani recorded it in al-Mu'jam al-Kabir within a long hadith that has already appeared in the chapter on funerals; its chain contains Layth bin Abi Sulaym, who is thiqah (trustworthy) but a mudallis (one who conceals defects in the chain); the remaining narrators of this narration are thiqat (trustworthy).
