Traditionalists tend to limit the Qur’an to a specific area, culture and/or era, by their limited understanding and semantic distortions.
For example, if there was a verse that said the Sky is Green, they’ll twist the verse to say that it means Blue, by saying that since both Green and Blue are colours, that colour is simply what is intended by this verse and that it’s Blue, as the Sky appears blue for them everyday, however, such a verse could very well be referring to a phenomenon in the Sky causing some of it to become green, if the reference is just colour then it can meaning absolutely any colour not just Blue.
There is actually a verse that the typical Traditionalist linguist disinterprets, as it’s actual understanding contradicts their regional-bound Séance (scientific understanding) and seems vague when they only view from their Mesopotamian and/or Levantine medieval milleu lens. The verse is as follows.
القرئان سورة الرحمن 35
يُرْسَلُ عَلَيْكُمَا شُوَاظٌ مِّن نَّارٍ وَنُحَاسٌ فَلَا تَنتَصِرَانِ
• Hilali & Khan
There will be sent against you both, smokeless flames of fire and (molten) brass, and you will not be able to defend yourselves.
Surah Ar-Raḥmān (55), ʾĀyah 35
This verse says A shuwāẓ (flame) of nār (fire) and نُحَاسٌ (nuḥās (copper)), the traditionalists who limit the context of the Qur’an to this small part of the world tend to disinterpret nuḥās as merely “smoke” here, which actually makes it more ambiguous, because which “smoke” is it? “Smoke” from what? While it’s pan-textually understood as “copper” in every other verse. Now of course, I’m not saying it’s referring to solid copper metal here, as there are different states of copper.
This verse specifically mentions that it’s a flame of fire and copper, so it can’t be referring to solid copper metal, but to a flame produced from it, which is something not visible from Arabia in the night sky, but something quite similar to it is visible only in the deep North i.e. Scandinavia, Greenland and Iceland, known as the Aurora Borealis.
And when understanding this verse from a wider lens and not from the perspective of the medieval levantine/mesopotamian milleu, this verse can understood better without semantic distortion, and thus can understand why it says copper (Cu). When copper (Cu) is burnt with fire, it produces a green flame, copper itself is initially brown, but when it is oxidised it turns green, for example the statue of liberty is made of copper, but since it has stood in the open air for over a century, it looks green because it got oxidized over time.
Orichalcum (mountain copper) is a type of copper found on mountains, the word orichalcum is a greek world that means mountain copper, this produces a green fire when burnt.
Orichalcum (“mountain copper”) or aurichalcum (“gold copper”) was a metal used in coins during ancient times. Orichalcum was a golden-yellow coloured mixture consisting of both copper and zinc and referred to as brass. The Romans were the first to make coins from orichalcum and were attracted to the metal due to its close resemblance to gold.
According to the Greek philosopher Plato (428/427-348-347 BCE), orichalcum was only second in value to gold. Ancient writers were at odds over whether or not orichalcum was a natural ore or made up of different metals.

This image is from a scene in the Aquaman 2 movie, this image shows green hot flowing rivers, these rivers are formed as a result of burning orichalcum to heat up the Earth and cause climate change, besides this waves of an aurora borealis are primarily green in the sky, the same colour as a green flame produced from burning copper, and the way they flow is like glowing rivers in the sky, so the verse is most likely referring to the aurora borealis or some sort of flares/projectiles of copper and fire that produce a green flame, and if it’s the aurora borealis then that could be why it mentions copper, since the flame produced from burning copper has the closest resemblance to the aurora borealis.
However, since most Traditionalists do not understand chemistry, and even the colour of a flame produced from copper, they are bound to interpret the verses in a way that fits their limited paradigm while the word they interpret looses it’s semantic meaning in the interpretation and translation.
