Is it permissible to advance the time of the Isha prayer due to its lateness in Norway during summer, especially when returning from work exhausted and having to go to work early?

It is not permissible for a wife to offer the prayer before its prescribed time merely due to work fatigue. This is because performing the prayer must be within its designated time, and it is not permissible to offer it earlier or delay it unless there is a valid excuse such as travel, illness, or the like.
