Is it permissible for the one in i'tikaf (spiritual retreat in the mosque) to go out to wash his hands?

Question : Is it permissible for the Shaykh to take a fee for his hand?

Answer : The author says it is not permissible, because he has a choice in that matter. However, it may be said that in some cases he has no choice but to do so, such as if he eats food that is very greasy; in that case, he must go out. He may not have napkins, and napkins do not clean completely anyway. Yes.
