Is a mother sinful for abstaining from intercourse due to menopause and its resulting physical symptoms, and is a father entitled to force her into intercourse in this manner, and what is the religious duty of the daughter in this situation, and is marriage based solely on intercourse?

A wife is not permitted to refuse her husband's bed without a valid excuse. The warning regarding the angels' cursing applies to refusal without a valid excuse. Marriage is not solely based on the marital bed; rather, it is one of its great purposes for chastity. The questioner should strive to reconcile her parents, remind her mother of the obligation to obey her husband unless there is an excuse, and advise her father to excuse his wife and consider her condition. If she does not fulfill his needs, he should marry a second wife.
