Sahih al-Bukhari, Book 72, Hadith 42 (In-Book) ⓘ
Narrated Ibn `Umar: The Prophet cursed the one who did Muthla to an animal (i e., cut its limbs or some other part of its body while it is still alive).
تَابَعَهُ سُلَيْمَانُ عَنْ شُعْبَةَ، حَدَّثَنَا الْمِنْهَالُ، عَنْ سَعِيدٍ، عَنِ ابْنِ عُمَرَ، لَعَنَ النَّبِيُّ صلى الله عليه وسلم مَنْ مَثَّلَ بِالْحَيَوَانِ. وَقَالَ عَدِيٌّ عَنْ سَعِيدٍ عَنِ ابْنِ عَبَّاسٍ عَنِ النَّبِيِّ صلى الله عليه وسلم.
