“Whatever is below the ankles from the lower garment will be in the Fire.” (Al-Bukhāri, no. 5787)

Abu Dharr (radiyallāhu ‘anhu) narrated that Allah’s Messenger (salallāhu ‘alaihi wasallam) said: “There are three to whom Allah will not speak on the Day of Resurrection, He will not look at them, He will not purify them―and for them is a painful punishment: The one who reminds others of what he has given them, the one who allows his garment to fall below his ankles, the trader who sells his products by making false oaths.” (Muslim no. 106, An-Nasā’ī, no. 2564)
