Mukhtasar Bukhari (Abridged) 1313 — Cheating even a little in war

Narrated Abdullah bin Amr (may Allah be pleased with them) that: There was a man assigned to the belongings of the Prophet (peace and blessings of Allah be upon him), his name was "Karkarah". Then he died, so the Prophet (peace and blessings of Allah be upon him) said: "He is in Hell." Then people began to look into his condition, and they found a cloak (sheet) among his possessions from the war booty, which he had taken deceitfully.
