Musannaf Ibn Abi Shaybah 40731 — Reports on the Khawarij

Sayyiduna Sa'd bin Malik (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) mentioned Dhu al-Thudayyah, who was with the people of the River, and said about him: "He is the devil of the pit. A man of the tribe of Bajilah, named al-Ashhab or Ibn al-Ashhab, will throw him into the pit. He will be a sign among an oppressive people."
