Is it permissible for a wife to conceal from her husband news concerning herself or her family, under the pretext that it is a secret? And is it obligatory to fulfill a promise made to children not to inform their father about their mistakes, even if it has negative consequences? What are the limits of concealing secrets from one's husband?

A wife is permitted to conceal from her husband matters pertaining to herself or others, especially if she has been entrusted with their secrecy. Indeed, it is not permissible to disclose such matters if their disclosure would cause harm or be a disregard for the right of the person whose secret it is. This includes anything that does not relate to the husband's right or result in the forfeiture of a right for him. As for concealing the children's behaviors from the father, the overriding interest should be considered. If the mother has promised the son not to tell his father, hoping that he will abandon the behavior, then she should not inform him, in fulfillment of her promise. If there is a compelling interest in informing him, then it should be done in a manner that the son does not perceive.
