(60) بَابُ إِشْعَارِ الْبُدْنِ فِي شَقِّ السَّنَامِ الْأَيْمَنِ، وَسَلْتِ الدَّمِ عَنْهَا،60 Subchapter: Marking sacrificial animals on the right side of the hump and letting blood flow
Hadith Q2575
ضِدَّ قَوْلِ مِنْ زَعَمَ أَنَّ إِشْعَارَ الْبُدْنِ مُثْلَةٌ، فَسَمَّى سُنَّةَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مُثْلَةً بِجَهْلِهِ
Contrary to the statement of that scholar who thinks that marking is mutilation. In this way, due to his ignorance, he has called the Sunnah of the Prophet Muhammad (peace be upon him) mutilation.
