What is the ruling of Islamic law regarding a wife remaining with her husband after he has divorced her three times, one of which was in a state of extreme anger, and another was made conditional upon a repeated event, along with forgetting the details of the second divorce?

The first and second divorces are valid, and the wife's forgetting the reason for the divorce does not affect their validity. As for the third: if the husband was unconscious at the time, his divorce is not effective; otherwise, it is effective. A conditional divorce takes effect when the condition is met.

Therefore, it is not possible to definitively confirm her major irreconcilable divorce from her husband. Thus, it is advisable to consult scholars directly or present the matter to a Sharia court.
