It was narrated that `Ali (رضي الله عنه) said: The Messenger of Allah (ﷺ) commanded us to examine the eyes and ears [of sacrificial animals] and not to sacrifice one that was blind in one eye, or al-muqabalah, or mudabarah, or sharqaʼ, or kharqaʼ. Zuhair said: I said to Abu Ishaq; Did he mention the one with its nose [or ear or lip] cutoff? He said: No. I said: What is al-muqabalah? He said: One that has the edge of its ears cut. I said: What is al-mudabarah? He said: One whose ears are slit from the back, I said: What is al-sharqa? He said: One whose ears are slit in two lengthwise, I said: What is al-kharqa`? He said:One that has a round hole in its ear as a distinguishing mark.
