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.
Malik, Abu Dawud and Nasa’i transmitted it.
