Musnad Abu Ya'la al-Mawsili 160:26

'Amr ibn al-Dahhak narrated to us, my father narrated to us, 'Abd al-Hamid ibn Ja'far informed us, he said: I heard Abu al-Jahm al-Qawwas narrating to my father—and he was a Persian man with a heavy tongue, and he was one of the companions of Abu Hurayrah—he said: I heard Abu Hurayrah saying: I heard the Messenger of Allah (peace and blessings of Allah be upon him) saying: "A mine will appear in the land of Banu Sulaym, called Fir'awn or Far'an—and that was in the tongue of Abu al-Jahm, close to the [word] 'al-Sawa'—the worst of people will go out to it, or the worst of people will be gathered to it."
