The Prophet (ﷺ) said: Hanging down is in lower garment, shirt and turban. If anyone trails any of them conceitedly, Allah will not look at him on the Day of Resurrection.
Sunan Abi Dawud Book 34, Hadith 75
← Previous Hadith I asked Abu Sa'id al-Khudri about wearing lower garment. He said: You have come to the man who knows it very well. The Messenger of Allah (ﷺ) said: The way for a believer to wear a lower garment is to have it halfway down his legs and he is guilty of no sin if it comes halfway between that and the ankles, but what comes lower than the ankles is in Hell. On the day of Resurrection. Allah will not look at him who trails his lower garment conceitedly.
