Narrated Busr ibn Artat: Junadah ibn AbuUmayyah said: We were with Busr ibn Artat on the sea (on an expedition). A thief called Misdar who had stolen a bukhti she-camel was brought. He said: I heard the Messenger of Allah (ﷺ) say: Hands are not to be cut off during a warlike expedition. Had it not been so, I would have cut it off.
