‘Amr b. Shu'aib, on his father’s authority, said that his grandfather told that God’s Messenger, Abu Bakr and ‘Umar burned the belongings of anyone who was dishonest about booty and beat him.
‘Abdallah b. ‘Amr told that when God’s Messenger gained booty he ordered Bilal to make a public announcement, and when the people brought their booty he would take a fifth and divide it. One day a man brought a halter of hair after that and said, “Messenger of God, this is part of the booty we got.” He asked whether he had heard Bilal making announcement three times, and when he replied that he had, he asked what had prevented him from bringing it. He made some excuse, so he said, “You must bring it yourself on the day of resurrection, for I shall never accept it from you.”
Yazid b. Khalid told that when one of God’s Messenger’s companions died at the battle of Khaibar they mentioned the matter to him and he replied, “Pray over your companion.” When the people looked perplexed at that he said, “Your companion was dishonest about booty in God’s path.” They searched his belongings and found some Jewish beads not worth two dirhams.
