It was narrated from ‘Ali bin Ab Talib, may Allah be pleased with him, that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: “Do not sacrifice an animal with its ears slit from the front, an animal with its ears slit from the back, an animal with its ears slit lengthwise, an animal with a round hole in its ears, or an animal with one bad eye.” (Hasan)
