Musannaf Ibn Abi Shayba 38:165

Yahya ibn Abi Bukayr narrated to us, he said: Ibn 'Uyaynah narrated to us, he said: al-'Ala' ibn Abi al-'Abbas narrated to us, he said: I heard Abu al-Tufayl informing from Bakr ibn Fawaris from Sa'd ibn Malik, who said: The Messenger of Allah (ﷺ) said—and he mentioned Dhu al-Thudayyah who was with the people of the river (al-Nahrawan)—he said: "The devil of the ravine, a man from Bajilah will drag him out, who is called al-Ashhab or Ibn al-Ashhab; a sign of evil among a people who are oppressors." 'Ammar al-Duhni said, when he (someone) denied it: A man from Bajilah came. He said: And I think he said from Dahn, who is called al-Ashhab or Ibn al-Ashhab.
