Lengthening the garment below the ankles for a man is forbidden in two situations and the texts are clear: (1) if done out of arrogance (khuyala''), it is a major sin and Allah does not even look at the doer on the Day of Judgement — "Allah will not look on the Day of Resurrection at the one who lets his garment trail in arrogance." ([al-Bukhari 5788](/hadith/bukhari/5788), Muslim 2087); (2) if done without arrogance — merely out of habit — it is still forbidden, on the general hadith: "Whatever is below the ankles of the izar is in the Fire." ([al-Bukhari 5787](/hadith/bukhari/5787)). The two hadiths are not in contradiction: the first specifies the harsher punishment for the one who does it out of pride; the second establishes the general prohibition for everyone. Some scholars restricted the prohibition to only the case of arrogance, but the apparent meaning of the second hadith — its generality and its absence of any qualifier — is what the strongest evidence supports. The garment of a Muslim man should fall to mid-shin, with no harm if it reaches the ankles (the upper bone), and what is below the ankles is forbidden. This applies equally to thawb, trousers, and any garment.
