Does a conditional divorce take effect if a man utters it without the intention of it taking effect, but with a feeling of an incidental intention such as ostentation?

If you told your wife something without intending to initiate a divorce, then nothing has occurred. What came to your mind about this is a satanic whisper (waswasa), especially since you suffer from obsessive thoughts (waswasa). A person afflicted with waswasa, even if he utters clear words of divorce, his divorce does not count. So, repel these whispers.
