"Do not sacrifice and animal with its ears slit from the front, and animal with its ears slit from the back, an animals with its ears slit lengthwise, and animal with a round hole in its ears, or an animal with one bad eye." (Using translation from Nasāʾī 4375)
عَنْ رَسُولَ اللهِ ﷺ قَالَ «لَا يُضَحَّى بمُدَابَرَةٍ وَلَا مُقَابَلَةٍ وَلَا شَرْقَاءَ وَلَا خَرْقَاءَ وَلَا عَوْرَاءَ»
