All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
Shaykh Ibn Taymiyyah is of the view that the general Ahadeeth that prohibit wearing clothes below the ankle are restricted by the Ahadeeth that prohibit doing so out of pride and arrogance. Therefore, if wearing clothes below the ankle is for the purpose of pride and showing off, then this is forbidden, and if it is not for this purpose, then it is not forbidden.
For more benefit, you may refer to the book of Shaykh Ibn Taymiyyah entitled Sharh Al-'Umdah, and for the view of Shaykh Ash-Shawkaani please refer to his book entitled 'Nayl Al-Awtaar'.
Allaah Knows best.
