Hadith 48.2
Prayer
'Ali said, “God’s Messenger enjoined us to pay great attention to the eye and the ear, and not sacrifice an animal with a slit which leaves something hanging at the front or back of the ear, or with a lengthwise slit or a perforation in the ear." Tirmidhi, Abu Dawud, Nasa’i, Darimi and Ibn Majah transmitted it, but Ibn Majah's words ended with "and the ear.”
وَعَنْ عَلِيٍّ قَالَ: أَمَرَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ نَسْتَشْرِفَ الْعَيْنَ وَالْأُذُنَ وَأَلَّا نُضَحِّيَ بِمُقَابَلَةٍ وَلَا مُدَابَرَةٍ وَلَا شَرْقَاءَ وَلَا خَرْقَاءَ. رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ وَالنَّسَائِيُّ والدارمي وانتهت رِوَايَته إِلَى قَوْله: وَالْأُذن
