Chapter : It to forbidden to trail one's garment out of conceit or pride.
Muslim b. Yannaq reported that Ibn Umar saw a person trailing his lower garment, whereupon he said: From whom do you come? He described his relationship (with the tribe he belonged) and it was found that he belonged to the tribe of Laith. Ibn Umar recognised him and said: I heard Allah's Messenger (may peace be upon him) with these two ears of mine saying: He who trailed his lower garment with no other intention but pride, Allah would not look toward him on the Day of Resurrection.
