What is the ruling on the relationship that the mother is having with a foreign man before her official divorce is finalized, and is their marriage permissible in the future, and how can she be dealt with regarding this matter?

Efforts should be made to reconcile the parents, seeking help through prayer, relatives, and virtuous individuals. Divorce occurs the moment the husband utters it, and once the waiting period (iddah) ends, the woman is permitted to marry another man; court procedures are for documentation only. The mother is allowed to marry another man after the iddah ends, provided the marriage fulfills its conditions, such as having a guardian (wali) and witnesses. It is not permissible for the mother to be in a relationship with a non-mahram man outside the framework of marriage. If this is proven, efforts should be made to rectify her situation kindly and without direct confrontation, but rather by reminding her through admonitions or lectures. Parents are not permitted to prevent their children from maintaining ties with either parent, and obedience is not obligatory in this wrongdoing, but wisdom should be sought in establishing these ties.
