A while back, almost 3 years ago, I had an argument with my wife and after the argument we let each other be. I went to another side in the room and was just thinking about what was going on and I Found myself mouthing the words “I divorce you”, randomly numerous times. Again, I was mouthing the words and not actually saying them. I can’t even remember how those words ended up in my mouth. Then one time the words actually came out to the point where I was able to hear them, like a small whisper. At the time, I remember being absolutely certain that I only heard the words once whereafter I immediately stopped. It was just a whisper that only myself was able to hear as I was mouthing these words and I remember stopping immediately because I actually heard the words come out. At that moment, I did some research and found out this counts as one divorce and my wife and I made up immediately and proceeded with our marriage. Now years later, I find myself thinking about this situation and whether I may have said and heard those words more than once. At the time that it happened, I was confident it was only said once, but now I get worried that I may have said it multiple times. I'm not sure if these are whispers from Shaytaan. Please advise. JazakAllah Khair.
