It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that some people saw a fire in the graveyard and went there. They saw that the Messenger of Allah (peace and blessings be upon him) was inside the grave, saying: "Hand your companion over to me (that is, lower him into the grave)." And this was the man who was "awwah" (that is, one who wept much and raised his voice in the remembrance of Allah). This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.
