Sahih al-Bukhari 5558

Ādam ibn Abī Iyās narrated to us: Shuʿbah narrated to us: Qatādah narrated to us, from Anas, who said: “The Prophet ﷺ offered two white-and-black rams as sacrifices. I saw him place his foot on their sides, invoke God’s name, and proclaim His greatness; then he slaughtered them with his own hand.”
