Is what was uttered by me, the word "divorce," without prior intention, but rather as a slip of the tongue—given your knowledge of my suffering from obsessive-compulsive disorder—considered an oath that entails a legal ruling?

We advise you to completely disregard the whispers (of Shaytan/waswas), to stay away from all forms of swearing oaths, and not to delve into veiled allusions to divorce. Nothing is binding upon you because of what you uttered by mistake or slip of the tongue. The cure for waswas is to turn away from it and not to dwell on it.
