Benefits and Issues: Allah, the Mighty and Majestic, has made husband and wife as garments for one another, so to disclose each other's secrets before others is a very reprehensible act. Except in the case where, due to some Shar‘i necessity, one is required to mention something before a judge (qadi) or the like.
