Shaykh Ibn Uthaymeen was asked the following question:
Question: If [a person] conceals long pants in the socks that he is wearing over them, does he exit the prohibited Isbaal by this?
What is apparent is that there is nothing (wrong) in it. However, it is from (الورع ) cautiousness to leave it because he will remove the socks.
I (Ibn Saneed) said: If he takes off the socks, he will remove the pants.
So the Shaikh said: What is apparent is that there is nothing (wrong) in it
