Salamun Alaikum brother Sardar,
I note the comments shared in your post.
It is to be appreciated that the Quran was not primarily addressing a community from the polar region. For example, when the Quran provides similitudes of heaven it often talks about shades, fountains, rivers with a sense of 'coolness' that would be most alluring to the scorching heat afflicted desert Arabs. However, this 'coolness' would be meaningless to people from the polar region who long for heat!
Similarly, green coloured silk robes with gold embroidery (18:31) would be least alluring to many modern cultures today who have a different sense of fashion.
The primary audience of the Quran and their conditions must be appreciated.
The salaat of the Quran is based on 'periods of the day' not on minutes and seconds. There were no digital clocks in 7th century Arabia in the desert. These periods of the day have been clearly highlighted by the Quran.
[1]The Quranic style is also to converse with humankind in general and not to deal with every perceivable anomaly that could ever exist. It is unlikely that the majority of mankind will leave luscious green lands where the earth provides in abundance and go and find habitation on the polar tips of the planet or in capsules orbiting space. Humans naturally gravitate towards land that gives them respite.
With respect, I find Quranic arguments that are simply based on the premise that X cannot mean Y because we have isolated cases of Z unacceptable.
This would be no different from saying that the Quran cannot mean ‘bowing’ in salat when it uses the word 'ruku' simply because there are people that are handicapped and cannot bow down.
Where there are
anomalies such as isolated places where there are long periods / continuous days or nights where fasting / prayers can become very difficult / impossible,
then it is arguable that sensible judgments can be made. It is important to remember that the purpose of religion is
not to make things difficult (
harj - 22:78) for humans. It is the spirit and intention of an action which always takes precedent.
Our only responsibility is to do the best we can (istata'a - 64:16) from the best we hear (39:18)
I hope that helps, God willing
Joseph.
