`Sayyiduna Abu Huraira (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he (peace be upon him) said: A man was walking arrogantly with his hair and garment (lower garment) showing off, eventually he was swallowed by the earth. Then he will continue sinking in it until the Day of Resurrection. (Perhaps that man was from this Ummah, but the correct view is that he was from a previous Ummah.)
