The Messenger of Allah ﷺ enjoined upon us to pay great attention to the eye and both ears, and not to sacrifice a one-eyed animal, and an animal with a slit which leaves something hanging at the front or back of the ear, or with a lengthwise slit with a perforation in the ear. I asked AbuIshaq: Did he mention an animal with broken horns and uprooted ears? He said: No. I said: 'What is the Muqabalah ?' He replied: 'It has been cut from the back of its ear.' I said: 'What about the Sharqa'? He replied: 'The ear has been split.' I said: 'What about the Kharqa'? He replied: 'A hole is made (in its ears) as a distinguishing mark.'"
أَمَرَنَا رَسُولُ اللَّهِ ﷺ أَنْ نَسْتَشْرِفَ الْعَيْنَ وَالأُذُنَيْنِ وَلاَ نُضَحِّيَ بِعَوْرَاءَ وَلاَ مُقَابَلَةٍ وَلاَ مُدَابَرَةٍ وَلاَ خَرْقَاءَ وَلاَ شَرْقَاءَ قَالَ زُهَيْرٌ فَقُلْتُ لأَبِي إِسْحَاقَ أَذَكَرَ عَضْبَاءَ قَالَ لاَ قُلْتُ فَمَا الْمُقَابَلَةُ قَالَ يُقْطَعُ طَرَفُ الأُذُنِ قُلْتُ فَمَا الْمُدَابَرَةُ قَالَ يُقْطَعُ مِنْ مُؤَخَّرِ الأُذُنِ قُلْتُ فَمَا الشَّرْقَاءُ قَالَ تُشَقُّ الأُذُنُ قُلْتُ فَمَا الْخَرْقَاءُ قَالَ تُخْرَقُ أُذُنُهَا لِلسِّمَةِ
