Hazrat Muhammad bin Ishaq (may Allah have mercy on him) states that the Messenger of Allah (peace and blessings be upon him) returned the hand of Hazrat Khubaib bin Asaf (may Allah be pleased with him) to its place, which had been cut off from between the neck and the shoulder on the day of the Battle of Badr. So the Messenger of Allah (peace and blessings be upon him) returned it. That place appeared as if there was only a slight mark.
