Karkara, a man who was in charge of the Prophet's belongings, died, and the Prophet (may Allah's peace and blessings be upon him) informed that he would be in Hellfire being punished for his sin, or that would be the case if Allah did not forgive him. So, the Companions went to find out the reason, and behold! They found in his place a cloack which he had stolen from the war booty.
