It is narrated from Hazrat Hudhaifa (may Allah be pleased with him) that the tribe of Mudar will not leave on earth any righteous servant of Allah without putting him into trial and destroying him, until Allah will impose upon them an army of His that will humiliate them, and not even the side of a mound will be able to save them. A man said to him, "Servant of Allah! You are saying this even though you yourself belong to the tribe of Mudar?" He replied, "I am only saying what the Noble Prophet (peace and blessings be upon him) has said."
