I heard the Prophet (ﷺ) saying, "There are three to whom Allah will neither speak on the Day of Resurrection nor will look at them nor purify them (i.e., of their sins), and they will be severely tormented." When he repeated this (statement) thrice, Abu Dharr (May Allah be pleased with him) said: "They are doomed and destroyed! (But) who are they, O Messenger of Allah (ﷺ)?" He said, "One whose lower garment trails, one who boasts of kindness shown to another; and one who promotes sale of his business by taking false oaths."
