It is narrated from Sayyiduna Zayd bin Khalid al-Juhani (may Allah be pleased with him) that on the day of Khaybar a man from among the Companions of the Prophet (peace and blessings be upon him) died. The people mentioned him to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Pray the funeral prayer over your companion (that is, I will not pray it)." On hearing this, the people's faces changed (with fear and astonishment). He (peace and blessings be upon him) said: "This companion of yours committed treachery in the way of Allah (with the spoils of war)." We searched his belongings and found some beads of the Jews' necklaces that were not worth even two dirhams. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but most probably they did not record it.
