I witnessed sacrificing along with the Messenger of Allah ﷺ at the place of prayer. When he finished his sermon, he descended from his pulpit, and a ram was brought to him. The Messenger of Allah ﷺ slaughtered it with his hand, and said: In the name of Allah, Allah, is Most Great. This is from me and from those who did not sacrifice from my community. (Using translation from Abū Dāʾūd 2810)
شَهِدْتُ مَعَ رَسُولِ اللهِ ﷺ الْأَضْحَى بِالْمُصَلَّى فَلَمَّا قَضَى خُطْبَتَهُ نَزَلَ مِنْ مِنْبَرِهِ وَأَتَى بِكَبْشٍ فَذَبَحَهُ رَسُولُ اللهِ ﷺ بِيَدِهِ وَقَالَ بِسْمِ اللهِ وَاللهُ أَكْبَرُ هَذَا عَنِّي وَعَمَّنْ لَمْ يُضَحِّ مِنْ أُمَّتِي
