What is the legal ruling in Islamic law regarding wiping over the shoe and the Jermooq if they are worn one over the other, and what are the conditions for this wiping?

It is permissible to wipe over both the sandals and the socks together if they were worn after performing ablution (ṭahāra). If the sandals are removed, one may wipe over the socks. It is also permissible to wipe over the jurmūq (an outer slipper or overshoe) if it is worn over the khuff (leather socks).

The following conditions are required for the permissibility of wiping over the khuffayn (leather socks) and jawrabayn (socks): 1. That they were put on after a complete state of ritual purity (ṭahāra). 2. That they cover the entire feet up to the ankles. 3. That it is ordinarily possible to walk in them. 4. That they are permissible and pure. 5. That they are thick (not transparent). Some scholars permit wiping over them even if the skin of the foot can be seen through them.

The duration of wiping is one day and one night for a resident, and three days and nights for a traveler. The method of wiping is to lightly wipe over the top of the khuffayn or jawrabayn, once on each foot.
