What is the ruling on a woman who did not inform her husband before marriage about having a chronic illness, knowing that she is a relative of his and now has a newborn?

The pathological defect that necessitates an option [for annulment] is one that causes aversion in either spouse and prevents the purpose of marriage, which is mercy and affection. The conditions for rejection are: that the defect must have existed before the contract, that the other party was not aware of it, and that they did not consent to it or find pleasure in it after becoming aware. If some of these conditions are not met, the husband has no option but divorce or retention. If the conditions are met, he may reject her and reclaim the dowry from the one who deceived him. The existence of a child indicates a long companionship, which makes the concealment of the defect unlikely.
