What is the ruling on repeating the phrase "upon me be divorce" with the intention of studying and verifying whether divorce occurs by merely uttering it or if it must be contingent, due to doubt and waswasah (obsessive whispering), knowing that the intention was not to pronounce divorce or to intend it?

What happened to you is a natural occurrence that does not affect the validity of the divorce, because the condition for divorce to take effect is the speaker's intention to pronounce divorce with the words: "Upon me be divorce." As for merely repeating the words without the intention of pronouncing divorce, it has no effect. We advise you not to repeat the words of divorce, and to set aside doubt and obsessive whispers.
