Is it considered abandoning a sister in Islam and being responsible for her deviation if a Muslim wife is divorced due to ill-treatment, with the fear of her returning to her family's home and the potential deviation that might cause?

Marital life is not free of problems. Therefore, we call for patience with one's wife and seeking reward from Allah, for the Prophet, peace and blessings be upon him, said: "No believing man should hate a believing woman; if he dislikes one of her characteristics, he will be pleased with another." However, if cohabitation between the spouses becomes impossible and there is no hope of reconciliation, then there is no impediment to divorce, for it is permissible and legislated to resolve disputes.
