Right now, there are parts of the world where the sun does not set, or does not rise. How do Muslims in those regions observe Ramadan?
(Yeah, I know, I could probably get the answer from Google, but I figured if there’s any place where I could get a straight answer, it’s here.)
I can offer a previous thread on this subject.
I do know that people are exempt from fasting if doing so will endanger their health.
A relative of mine, who lives in a Scandinavian country, converted to Islam a few years back. During Ramadan, he follows Meccan time rather than local time, i.e. regarding sunrise and sunset. He told me this practice is considered perfectly A-OK by some major theologian at Cairo’s Al-Azhar University, which he (along with most of the Sunni world) considers a trustworthy authority.
