عن أسماء بنت يزيد الأنصارية رضى الله عنها قالت‏:‏ كان كم قميص رسول الله صلى الله عليه وسلم إلى الرسغ.‏((رواه أبو داود والترمذي))

Abu Sa'id Al-Khudri (May Allah be pleased with him) reported

Messenger of Allah (ﷺ) said, "The lower garment of a believer should be half way below the knees. He is guilty of no sin if they are up to the ankles. That which is below the ankles is in the Fire (of Hell). Allah will not look at one who allows his lower garment to trail out of vanity.[Abu Dawud].
