"The Prophet ﷺ came to Al-Madinah and they were in the habit of cutting the humps off of the camels and cutting the buttocks from the sheep. He said: 'Whatever is cut from an animal while it is alive, then it is dead flesh.'"  

قَدِمَ النَّبِيُّ ﷺ الْمَدِينَةَ وَهُمْ يَجُبُّونَ أَسْنِمَةَ الإِبِلِ وَيَقْطَعُونَ أَلْيَاتِ الْغَنَمِ قَالَ مَا قُطِعَ مِنَ الْبَهِيمَةِ وَهِيَ حَيَّةٌ فَهُوَ مَيْتَةٌ
