Is it part of one's religion to remain with a wife who has refused intimacy for a year without justification, and were her family entitled not to inform the husband of her mental disability before marriage, considering the presence of two children and the fear for them?

A wife's answering her husband's call to the bed is obligatory, and it is not permissible for her to refuse without a legitimate excuse. If a wife refuses without a legitimate excuse, she is considered disobedient (nashiz) and forfeits her right to maintenance. The husband then has the right to discipline her according to Islamic law. If the husband is unable to rectify her behavior, he may marry another woman or divorce her and marry someone else. Marriage may become obligatory for him if he fears falling into temptation.

Mild intellectual disability that does not reach the level of insanity is not among the defects that warrant annulment of the marriage. It is preferable to disclose it before marriage to prevent disputes.
