The Ruling on Wearing Short Pants
Question :
What is the ruling on wearing short pants during sports, for example, outside of the time for prayer while there is no threat of temptation? Please mention some proofs to support the answer?
Answer:
Our opinion is that it is not allowed to wear short pants that leave the thighs uncovered, either partly or mostly.
This ruling applies to playing sports or in the marketplace or to any other occasion, even outside of prayer. It is allowed to wear such shorts if one is inside one's own house doing one's work, but only if people cannot see him. The proof for this is the Hadith wherein the Messenger of Allah ﷺ passed by Al-Jarhad Al-Aslami, whose Izar was exposing part of his thigh. He ﷺ to him, said :
"Cover your thigh, for the thigh is 'Awrah."
And with Allah is the facilitation to do what is right.
