What is the criterion that differentiates between inner thoughts and explicit pronouncements in divorce, especially when there is doubt about its occurrence after thinking about it or discussing it with a friend?

The committee has reviewed your questions and learned from them that you suffer from waswas (obsessive whispering). We ask Allah for well-being and healing for us and for you. What you mentioned has no consequence, so disregard it. There is no cure for waswas other than abandoning it and turning away from it.
