How do people in Norway break the 24 hour in heir normal daily life?
Qoran says do the best you can according to the situation you find yourself in.
In most countries the 24 hour is broken like this:
Dawn. sunrise to Noon, -Dhahirati- afternoon, sunset-twilight- Ghasak/dark night.
If daylight is 24 hours or night time is 24 hours , then we still need to break it into sections like this:
getting up time, breakfast and work, dinner time, afternoon time , teatime and sleep.
If I was under these circumstances, I would do fasting from getting up to teatime. My salat will follow similar pattern to the sections above . Or feed the poor, help people instead of fasting.
GOD knows where we are and our intentions.
Sirat Al Mustaqeem-straight path is the main message to all humans and through all the messengers and that does not require natural conditions or specific timing.
The rest like salat, sawm,...etc,which helps our taqwa, depends on circumstances and abilities. Special circumstances do exist in the natural world . Qoran allows for this like it does for emergencies , other conditions,disabilities...etc.
GOD bless.
Peace.
