Did the divorce occur in the three mentioned cases, where the husband uttered the divorce conditional on a specific action, and another time the utterance was due to coercion, and in the third, it was in response to insults and a quarrel?

A conditional divorce takes effect when the condition it is tied to is met, according to the majority of scholars. The phrase "you are divorced" is an explicit statement by which divorce occurs without the need for intention. What the husband uttered regarding divorce under the influence of fear is not a religiously recognized coercion that would prevent the divorce from taking effect. It is not permissible for the wife to harm her husband or to request a divorce without a valid religious excuse. If the husband divorces his wife three times or more, a major irrevocable divorce has occurred, and she is not lawful for him until she marries another husband. If it is less than three, he may take her back before the 'iddah (waiting period) is complete. It is recommended to consult scholars in person to determine the most precise answer.
