Abu Dawud Book 8, Hadith Number 2704.

Narated By Zayd ibn Khalid al-Juhani : A man from the Companions of the Prophet (PBUH) died on the day of Khaybar. They mentioned the matter to the Apostle of Allah. He said: Offer prayer over your companion. When the faces of the people looked perplexed, he said: Your companion misappropriated booty in the path of Allah. We searched his belongings and found some Jewish beads not worth two dirhams.
