Removing nail polish before making wudoo'
Question

                We have heard some people saying that it is permissible for a 
woman to make wudoo' without removing her nail polish. 
What is your opinion?
Praise be to Allah.
If the nail polish forms an impermeable layer that prevents water from 
reaching the surface of the nail, her wudoo' is not valid unless she first 
removes it. If she wears something like henna that does not create an 
impermeable layer, then her wudoo' is valid.
