I met a person who had to close his bakery because his wife kept on fainting while baking in the bakery
He told me that he brought some healers to the bakery, his wife became well but after a week, she started to faint again.
They had to close the bakery.
Now they operate their cookies business from home. He told me that his wife does not faint anymore since they began reciting Ruqyah verses from the Noble Quran every day.
