"I saw him: - meaning the Prophet - "slaughtering them with his own hand, and placing his foot on their sides, pronouncing the name of Allah and saying: 'Allah Akbar,' (sacrificing) two horned, Amlah rams." (Sahih ) (Using translation from Nasāʾī 4417)
لَقَدْ رَأَيْتُهُ يَعْنِي النَّبِيَّ ﷺ يَذْبَحُهُمَا بِيَدِهِ وَاضِعًا عَلَى صِفَاحِهِمَا قَدَمَهُ يُسَمِّي وَيُكَبِّرُ كَبْشَيْنِ أَمْلَحَيْنِ أَقْرَنَيْنِ
