"The Messenger of Allah sacrificed two horned, Amlah rams, saying: 'Allah Akbar and pronouncing the Name of Allah. I saw him slaughtering them with his own hand, and placing his foot on their sides." I said: You heard it from Him? He said: Yes. (Sahih ) (Using translation from Nasāʾī 4415)  

«ضَحَّى رَسُولُ اللهِ ﷺ بِكَبْشَيْنِ أَمْلَحَيْنِ أَقْرَنَيْنِ يُكَبِّرُ وَيُسَمِّي وَلَقَدْ رَأَيْتُهُ يَذْبَحُهُمَا بِيَدِهِ وَاضِعًا عَلَى صِفَاحِهِمَا قَدَمَهُ» قُلْتُ أَنْتَ سَمِعْتَهُ مِنْهُ؟ قَالَ نَعَمْ
