Isbal (lengthening and trailing clothing below the ankles) is prohibited for men, whether they are garments, trousers, cloaks or whatsoever based on the general meaning of the saying of the Prophet (peace be upon him):
The part of an Izar which hangs below the ankles is in the Fire.

and Al-Bukhari. Also, the Prophet (peace be upon him) said:
Three persons whom Allah shall neither speak to on the Day of Resurrection, nor look at, nor purify, and they shall have a painful torment: he who reminds (the people) of what he gives, he who lets his izar (lower garment) hang below his ankles (out of pride) and he who sells his merchandise by false swearing”
Muslim in his Sahih (authentic) Book, and Imam
Ahmad in his Musnad (Hadith compilation). (Part No. 24; Page No. 13) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
