[Machine] The Prophet ﷺ used to sacrifice two sheep and would place his foot on their sides, then he would slaughter them with his own hand, saying "In the name of Allah, Allah is the Greatest."  

أَنَّ النَّبِيَّ ﷺ كَانَ يُضَحِّي بِكَبْشَيْنِ وَيَضَعُ رِجْلَهُ عَلَى صِفَاحِهِمَا فَيَذْبَحُهُمَا بِيَدِهِ وَيَقُولُ بِسْمِ اللهِ وَاللهُ أَكْبَرُ
