Abu Dawud Book 9, Hadith Number 2804.

Narated By Jabir ibn Abdullah : I witnessed sacrificing along with the Apostle of Allah (PBUH) at the place of prayer. When he finished his sermon, he descended from his pulpit, and a ram was brought to him. The Apostle of Allah (PBUH) 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.
