Musannaf Ibn Abi Shaybah 34542 — The virtue of the Ansar

Muhammad bin Ishaq (may Allah have mercy on him) said that the Messenger of Allah (peace and blessings be upon him) put back in its place the arm of Sayyiduna Khubayb bin Yasaf (may Allah be pleased with him), which had been cut between the neck and the shoulder on the day of the Battle of Badr. The Messenger of Allah (peace and blessings be upon him) put it back, and the place then looked as if there were only a faint mark.
