What is the ruling of Islam regarding how to deal with a wife who was kidnapped and subjected to rape, and what is the advice directed to her husband and father to treat her with kindness and protect her from ill talk, especially after her return when she is in a deteriorating physical and psychological state?

The fundamental principle for a Muslim is soundness (integrity) and the obligation to think well of them. It is not permissible to think ill of a woman or accuse her of committing indecency without clear proof. If, however, indecency occurred due to coercion, then there is no sin upon her, as accountability is lifted under duress. The statement that she is not suitable as a wife because of what happened to her is incorrect. Caution must be exercised regarding a woman's presence in places where she might be exposed to danger.
