The Ruling on the Hajj of a Worker and a Police Officer without the Permission of their Authorities
Is it permissible for a police officer to perform Hajj without the permission of his authorities?
There is absolutely no Hajj for the worker and the police officer unless they have the permission of their authorities. It is not permissible for them to perform Hajj without the permission of their authorities, because their time is the right of the authority figures. It makes no difference whether the Hajj is an obligatory Hajj or a voluntary Hajj. This is also because the acts of Hajj hinder the worker and the police officer from certain things that they are required to do during this time.
