Narrated Ali ibn Abu Talib: The Prophet صلی اللہ علیہ وسلم prohibited to sacrifice an animal with a slit ear and broken horn. Abu Dawud said: The narrator Jurayy (b. Kulaib) is Sadusi, and belongs to Basrah. No one narrated traditions from him except Qatadah.

Narrated Ubayd ibn Firuz: I asked al-Bara ibn Azib: What should be avoided in sacrificial animals? He said: The Messenger of Allah صلی اللہ علیہ وسلم stood among us, and my fingers are smaller than his fingers, and my fingertips are smaller than his fingertips. He said (pointing with his fingers): Four (types of animals) should be avoided in sacrifice: A One-eyed animal which has obviously lost the sight of one eye, a sick animal which is obviously sick, a lame animal which obviously limps and an animal with a broken leg with no marrow. I also detest an animal which has defective teeth. He said: Leave what you detest, but do not make it illegal for anyone. Abu Dawud said: (By a lean animal mean) and animal which has no marrow.
