Marriage in Islam, as it has been referred to by Allah in the Qur’an, is a solemn contract, which the parties should honor and respect, and this includes respecting privacy and confidentiality of each spouse. It is therefore clearly wrong for a spouse to divulge matters related spousal relations to anyone else. The only exception is when it is a clear case of spousal abuse, where one is allowed to disclose certain matters and that too only to the extent required ---only to those who are in a position to restore or redress them. In all other cases, it is indeed a most heinous sin to do so.

If therefore your husband is divulging such matters to his maternal aunt, he is clearly violating the rules of Islamic ethics governing husband and wife relations. Islam clearly forbids divulging such matters to anyone. By such acts, one is exposing himself to the wrath of Allah, for as the Prophet, peace be upon him, says, “One of the worst of men (in the sight of Allah) is he who, after having intimate union with his wife, talks about it to others.” In yet another tradition, the Prophet, peace be upon him, once asked his companions, “Perhaps some of you men establish conjugal relations with their wives and talk about it to others; perhaps some of you women speak about your relations with your husbands with others? When they remained silent, he said, “To do so is not different from that of a he-devil copulating with a she-devil in public view!” In other words, Islam considers it as an abominable behavior not befitting a believer or a decent human being. May Allah endear to our hearts faith and good conduct, and may He make us abhor and shun all unseemly and abominable actions and behavior-aameen.
