It was narrated that `Ali bin Abi Talib (رضي الله عنه) said:
The Messenger of Allah (ﷺ) forbade sacrificing an animal with its ears slit from the front, an animal with its ears slit from the back, an animal whose ears are slit in two lengthwise, an animal with a round hole in its ear, and an animal with its nose [or ear or lip] cut off.
