Is there a Prophetic supplication to nullify the envy that afflicted a happy marriage which lasted 12 years and produced three children, and transformed into discord, hatred, and insistence on divorce despite reconciliation attempts and family intervention?

If the wife's behavior suddenly changes without an apparent reason, it might be due to envy (hasad). Ruqyah Shariah (Islamic exorcism) is recommended to nullify the envy, such as reciting the two Mu'awwidhatayn (Surahs Al-Falaq and An-Nas), and what is authentically narrated in Sahih Muslim: "Bismillahi arqeeka, min kulli shayin yu'dheeka, min sharri kulli nafsin aw 'ayni hasid, Allahu yashfeeka, bismillahi arqeeka" (In the name of Allah I perform ruqyah for you, from everything that harms you, from the evil of every soul or envious eye, may Allah cure you, in the name of Allah I perform ruqyah for you). This should be accompanied by continuous ruqyah and frequent supplication for her healing.
