Section : Animals to Be Avoided as Sacrifices.

Yahya related to me from Malik from Amr ibn al-Harith from Ubayd ibn Fayruz from al-Bara ibn Azib that the Messenger of Allah, may Allah bless him and grant him peace, was asked what animals should be avoided as sacrifices. He indicated with his hand and said, "Four." Al-Bara pointed with his hand and said, "My hand is shorter than the hand of the Messenger of Allah, may Allah bless him and grant him peace. A lame animal whose lameness is evident, a one-eyed animal which is clearly one-eyed, an animal which is clearly ill, and an emaciated animal with no fat on it."
