حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى الصَّنْعَانِيُّ، حَدَّثَنَا سَلَمَةُ بْنُ رَجَاءٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي وَاقِدٍ اللَّيْثِيِّ، قَالَ قَدِمَ النَّبِيُّ صلى الله عليه وسلم الْمَدِينَةَ وَهُمْ يَجُبُّونَ أَسْنِمَةَ الإِبِلِ وَيَقْطَعُونَ أَلْيَاتِ الْغَنَمِ قَالَ ‏"‏ مَا قُطِعَ مِنَ الْبَهِيمَةِ وَهِيَ حَيَّةٌ فَهُوَ مَيْتَةٌ ‏"‏ ‏.‏

Narrated Abu Waqid Al-Laithi: "The Prophet (PBUH) 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.'" Translation Not Available
