Sulaym bin Aghdar سليم بن أخضر · The Book on Sacrifices

"I attended the Eid Al-Adha' with the Prophet (ﷺ) at the Musalla. When he finished his Khutbah, he descended from his Minbar and was given a male sheep. The Messenger of Allah (ﷺ) slaughtered it with his hand and said: 'Bismillah, Wa Allahu Akbar, this from me and whoever does not slaughter from my Ummah.'"
