Quick mental health question

Asalamualaikum Hypothetically in Islam if a hypothetical man has an OCD he has a thought that” if he doesn’t or does do that then “divorce” “ so he does stuff for example it could be anything like opening the door multiple times or switching the light off multiple times after. the fact that this hypothetical man listens to the thought and act on it do anything ? Or starts to do with action or is in the middle of it and stop himself does that do anything? or if he can’t do the action for any reason? there’s no intention at all of Divorce ,does that do anything in all scenarios or anything similar? May you be rewarded
