Musnad Ahmad

Yazid Dhu Misr says that once I went to Hazrat Utbah (may Allah be pleased with him) and said, "O Abu al-Waleed! I went out in search of a sacrificial animal, but I could not find any animal except one whose tooth was broken. What is your opinion?" He replied, "Why did you not bring it to me?" I said, "Subhan Allah! The sacrifice would be valid from your side but not from mine?" He said, "Yes! Because you have doubt, and I have no doubt. The Prophet (peace and blessings be upon him) only forbade Musaffarah, the horned animal whose horn is uprooted, Bukha’a, Mushee’ah, and Kasra’." Musaffarah means the animal whose ear is cut from the root and its hole is visible. Bukha’a means the animal whose eye is defective. Mushee’ah means the animal that, due to weakness and helplessness, cannot walk with the goats. Kasra’ means the animal whose bone is broken and cannot walk straight. The previous hadith is narrated from this second chain.
