Is it permissible to perform Wudu while wearing a Hijab and socks, or is it necessary to remove them and then perform the necessary parts of Wudu such as Massah?
If your Hijab and socks prevent you from performing proper Masah (مَسح Wiping) over your head and feet, then you must remove any cloth with prevents wiping over your head and feet which is must in Wudu.
Wassalam.
