Is a divorce that was issued twice with the intention of prevention and threat valid, bearing in mind that one of the times was with the intention of divorce in a state of extreme anger, but he does not remember the exact wording, and what is the ruling on the wife's condition of adorning herself and wearing a hijab that describes the body in exchange for returning?

What you mentioned about the two divorces on two different occasions: if there was a reconciliation (raj'ah) between them, then they are two divorces. If the second divorce occurred without a reconciliation, the majority of scholars hold that both divorces take effect, while some scholars are of the opinion that only one divorce takes effect. As for swearing by divorce with the intention of threat and prevention, the majority of scholars hold that divorce takes effect, while some hold that an expiation for an oath (kaffarat yamin) is due. Doubt regarding the intention or wording between what causes divorce to occur and what does not is not to be considered; the default is the continuation of the marital bond. There is disagreement regarding these issues, hence it is advisable to consult the Sharia court, as a judge's ruling resolves disagreements. One must be cautious about being lenient in uttering divorce. It is not permissible for the husband to approve of his wife adorning herself when going out or wearing what does not conform to Islamic law, and he bears the responsibility of safeguarding her religious commitment. Modern hijab often fails to meet some of the شرعي (Sharia-compliant) conditions.
