8 hadith found in 'The Promised Deliverer (Kitab Al-Mahdi)' of Sunan Abu-Dawud.

(4277) Narrated Ali ibn AbuTalib: The Prophet (peace_be_upon_him) said: A man called al-Harith ibn Harrath will come forth from Ma Wara an-Nahr. His army will be led by a man called Mansur who will establish or consolidate things for Muhammad's family as Quraysh consolidated them for the Apostle of Allah (peace_be_upon_him). Every believer must help him, or he said: respond to his sermons.
