[Machine] The Prophet ﷺ and his companions used to slaughter the animal with the right foot lifted, based on what remained of its hooves. This is mentioned in the hadith of Ibn Jurayj from Abu Zubair from Jabir, which is connected, and in his hadith from Abdul Rahman ibn Sabbit, which is transmitted.
أَنَّ النَّبِيَّ ﷺ وَأَصْحَابَهُ كَانُوا يَنْحَرُونَ الْبَدَنَةَ مَعْقُولَةَ الْيُسْرَى قَائِمَةً عَلَى مَا بَقِيَ مِنْ قَوَائِمِهَا حَدِيثُ ابْنِ جُرَيْجٍ عَنْ أَبِي الزُّبَيْرِ عَنْ جَابِرٍ مَوْصُولٌ وَحَدِيثُهُ عَنْ عَبْدِ الرَّحْمَنِ بْنِ سَابِطٍ مُرْسَلٌ
