Question: Assalamu alaykum
I may have chicken pox. Doctors urged not to take shower in case any infection happens, which would deteriorate the case further.
What do I do if I have wet dreams and need to take ghusl in this case?
Answer: Wa ‘alaykum as-salam wa rahmatullah wa barakatuh
I pray you are well.
If the doctors have advised you against having the shower in order to prevent the condition worsening, and if you find that you need to perform a ghusl after a wet dream then do the following:
1. Remove the impurity from your body using as little water as possible. This can be restricted to the area.
2. Rinse your mouth and nose normally, and then rub your whole body with a moist hand. This will count as a ghusl.
3. If (2) is not possible then you may perform Dry Ablution (Tayammum). Please see this answer for instructions. (Ibn ʿAbidin, Radd al Muhtar).
It might be a good idea to ask how long you need avoid having showers for. That way you won’t have to do this longer than necessary.
May Allah grant you the best of both worlds.
