The wudoo’ of one who has something impermeable on his hand etc.
Question

                If a person performs wudoo’ then finds that
  part of his hands etc. is covered with something impermeable, such as paint, that prevents
  water from reaching his skin, can he go ahead and pray, or does he have to remove it for
  every obligatory prayer, even though that involves hardship for him?
Praise be to Allah.The Muslim should make sure that water reaches his skin every time he
does wudoo’, and he has to remove anything that prevents this. People whose work
involves painting and so on can wear something on their hands to prevent them from getting
covered with paint.
