It is narrated from Sayyiduna Abu Tha'labah al-Khushani (may Allah be pleased with him); he said: I said: O Messenger of Allah, tell me what is lawful for me and what is unlawful for me. He (peace and blessings be upon him) looked me over from head to foot, then said: "Nuwaybitah." I said: O Messenger of Allah, is it a good nuwaybitah or a bad one? He (peace and blessings be upon him) said: "Rather, it is a good nuwaybitah. Do not eat the meat of the domestic donkey, nor of any predator with fangs."
