Musnad Ahmad 32:1221

Rawh narrated to us, Hisham narrated to us, from Muhammad, from Anas ibn Malik: "The Messenger of Allah (peace and blessings of Allah be upon him) stoned the Jamrah, then he slaughtered the sacrificial animals while the barber was sitting. Then he said to the barber—and Hisham described that— And he placed his hand on his forelock, so he shaved one of his sides, the right one, and he distributed it among the people. Then he shaved the other, and he gave it to Abu Talhah."
