Is it permissible to divorce a barren wife who concealed her infertility before marriage, due to the need for a child, and what is the ruling regarding the dowry paid to her in this case?

There is no sin or problem in divorcing a wife due to infertility if the divorce is out of necessity. She is entitled to all the rights of a divorced woman, and the husband has no right to demand anything from her dowry or her wealth except if she voluntarily offers it. Infertility is not considered among the defects that establish the right to annulment according to the majority of scholars, even though some consider it a defect. If it is considered a defect, the annulment of the marriage based on it requires that there be no indication of the husband's consent to it.
