Musannaf Ibn Abi Shayba 18:1241

Abu Bakr narrated to us, he said: Waki’ narrated to us, he said: ‘Imran bin Hudayr narrated to us, from Abu Mijlaz, who said: I said to a man while he was at his place of slaughter—meaning his place of destruction—a bridge or a wall: "So he cut off his nose, and he threw him down, so he paid his blood money."
