Sayyiduna Abu Barzah (may Allah be pleased with him) says: I heard the Prophet (peace and blessings be upon him) say: "There will be a person in my Ummah who will intercede for more people than Rabi'ah and Mudar, and there will be a person belonging to my Ummah who will be enlarged in Hell until he becomes one of its corners."
Ahmad recorded it, and its narrators are thiqat (trustworthy).
