The ruling on differing from the community regarding the length of the garment

Question:
May Allah reward you. The presenter says: You stated that the purpose of knowledge is action. So if I know that the Sunnah for the garment is that it should be to the middle of the shin, but I do not act upon it, am I a disbeliever in this state?

Answer:
No. The Sunnah for the garment is to the middle of the shin only. The Sunnah for the lower garment (izar) is to the middle of the shin. The lower garment of the believer is to the middle of the shin; this is the izar. Also, even if we say that this is general for the izar and the length is to the middle of the shin, the ankle is also a Sunnah. This is a Sunnah and this is a Sunnah. If the community has adopted the second Sunnah, which is to the ankle, it is not bad for you to differ from the community and to be among them wearing a garment that differs from theirs in this regard. As long as the community is upon a prescribed matter or a permissible matter, you are with them and you do not differ from them. Raising it to the shin, to the ankle, is a Sunnah. If the people have adopted it, adopt it and do not demand it of them. But if you are in a community that wears it to the middle of the shin, wear it and do not fluctuate.
