Jahdam bin al-Dahhak narrates: I passed by the place "al-Raji'" and saw an elderly man there. The people said: This is Sayyiduna al-Adda' bin Khalid bin Hawdhah (may Allah be pleased with him). He said: I have seen the Prophet (peace and blessings be upon him). I said: Describe his appearance to me. He replied: He had a beautiful beard. The narrator says: The Arabs use the word "sabalah" for the beard.
Imam al-Tabarani recorded it, and its chain contains narrators whom I do not know.
