Extreme waswasah

Asalamualaikum may Allah reward you In Islam if a man has waswasah about “divorce” and maybe as it’s always in his head, he says a normal word maybe to his wife for example he might say “hello” but because of the severe waswasah of the word “divorce” he accidentally starts with the letter “ “d” and maybe accidentally says “ “d ello” or maybe he does this with other words does that do anything. Furthermore what if another hypothetical man verbally says “if Allah or the prophet peace be upon me asks to “divorce” my wife” and he out loud says “I would” do it with no intention at all would that do anything
