Sayyiduna Zayd bin Khalid al-Juhani (may Allah be pleased with him) narrates: One of the companions of the Prophet (peace and blessings of Allah be upon him) passed away during the Battle of Khaybar. The people mentioned his death before the Prophet (peace and blessings of Allah be upon him), so the Prophet (peace and blessings of Allah be upon him) said: "You people perform the funeral prayer of your companion." At this, the faces of the people changed (i.e., they became worried). The Prophet (peace and blessings of Allah be upon him) said: "Your companion committed treachery in the way of Allah." (The narrator says) When we examined his belongings, we found a necklace belonging to the Jews, which was not even worth two dirhams.
