Ubaid bin Firoz asked Sayyiduna Bara’ (may Allah be pleased with him) about sacrificial animals: from which types of animals did the Messenger of Allah (peace and blessings be upon him) prohibit and dislike? He said: The Messenger of Allah (peace and blessings be upon him) stood among us and, gesturing with his hand in this manner—while my hand is smaller than his (peace and blessings be upon him)—he said: Four types of animals are not sufficient for sacrifice: (1) The cross-eyed one, whose cross-eyedness is obvious. (2) The sick one, whose sickness is obvious. (3) The lame one, whose lameness is obvious. (4) Such an emaciated animal that there is no marrow in its bones. I said: I also dislike defects in the horn, ear, or teeth. He said: Whatever you dislike, leave it, but do not declare it unlawful for others.
