Is a wife entitled to look at her husband's phone or private belongings, or is that considered a violation of his privacy?

A wife does not have the right to spy on her husband by searching his phone or belongings without his permission. This also applies to the husband, as no one is allowed to spy on the other except out of necessity to prevent an evil or avert a corruption. However, a wife using her husband's phone or looking at it without spying is not forbidden, unless the husband prevents her. It is permissible for a wife to ask her husband about the reason for his going out, his whereabouts, and who he is with, but the husband is not obligated to inform her. The marital relationship should be based on understanding, compassion, cooperation, trust, and having a good opinion of one another.
