Is it permissible for a person to allow another to spy on him and search his belongings without objection?

Spying is forbidden in Islamic law by the texts of the Quran and Sunnah. It is the act of prying into people's private lives and hidden secrets in their solitude and heedlessness without their permission, whether by looking, eavesdropping, or examining their writings and belongings. However, if permission is granted to search possessions, it is not considered spying, unless it leads to discovering something forbidden.
