The ruling on adding to the three washes in wudu, and does it invalidate the wudu?

Question:
May Allah reward you. Umm Anas asks about adding to the three washes in wudu without intention; does it invalidate the wudu?

Answer:
The wudu is not invalidated, but adding to the three washes is not permissible; because it is a bid'ah (religious innovation). However, if a person does it while forgetting, there is no blame on him, or if he is not certain that he performed three washes and he performs this wash, this is the door of precaution and exiting from doubt, so there is nothing wrong with that. As for if he does it intentionally while knowing that he has performed the three washes, this is a bid'ah and is not permissible. Yes.
