Hasan (may Allah have mercy on him) says that once Hazrat Abu Hurairah (may Allah be pleased with him) was narrating hadiths in front of his students when a man wearing a silk garment came and, standing near Hazrat Abu Hurairah (may Allah be pleased with him), said, "O Abu Hurairah! Do you have any verdict regarding this garment of mine?" He raised his head towards him and said, "The Truthful and Trusted, my beloved Abu al-Qasim (peace and blessings be upon him), informed me that a man, dressed in his precious robe, was walking arrogantly, boasting about himself, when suddenly Allah caused him to be swallowed by the earth, and now he will continue to sink in the earth until the Day of Resurrection."
