The Prophet (may Allah's peace and blessings be upon him) clarified that a Muslim man's Izār (whatever covers the lower half of a man's body) has three states: First: The recommended state is to reach halfway down the shin. Second: The permissible state without being disliked is to extend below that, down to the ankles, which are the two prominent bones at the joint of the shin and foot. Third: The prohibited state is to extend below the ankles, and there is a fear that one may be punished by the Fire. If worn out of arrogance, gloating, and transgression, then Allah will not look at him.
