Surah Al Kahf - Ayah No 96

Assalam o Alaikum 

Juma Mubarak. Let's seek refuge of Allah swt from all evils i.e. iblees, dajjal and their associates to the safest retreat of Al Kahf, The Cave of Hope.

In today's Ayah No 96, to prevent Gog Mgog entering into their land, Zulqarnain asked that nation to arrange for iron and copper. First, he leveled two high points (Arabic word صدفین) which is translated as mountains, cliffs etc for convenience), then asked them to blow until iron got red hot and then poured  molten copper over it. Again, it is construed traditionally as steel wall with slippery copper top making it impossible for Gog Mgog to scale. As traditional myth, since that time Gog Mgog are trying to negotiate that wall. If not a myth with anyone, I grew up with same imagery because Imam sb told me so. However, detailed description of this creature in Ahadith does not support this notion.

Let's see how basic sciences explain this coming together of hot iron and copper.

A piece of iron ordinarily will be attracted to a magnet, but when you heat the iron to a high enough temperature (called the Curie point), it loses its ability to be magnetized. Heat energy scrambles the iron atoms so they can't line up and create a magnetic field.

Data transmission through copper involves much more signal loss, especially at higher frequencies. The higher the frequency of electromagnetic waves through a conducting copper wire, the more the carrier waves travel only at the surface of the material. This physical phenomenon is known as the 'skin effect'.

So, we can assume that the barrier built by Zulqarnain at a particular high point was to resist electromagnetic waves at portal entry point into that land. Now relate this Hadith of taking to high points for refuge towards the end of times and recite Al Kahf extensively. 

Please note that scribe is not a scientist nor have qualification in Quranic interpretations. This is just an attempt to understand Al Quran/ Al Kahf by parting from traditional thinking (with complete respect for hitherto works on the subject) on the subject. Because, if our coming generations don't find relation of Quranic Truth with their modern way of thinking, they might go adrift from their core.

Only Allah knows the whole Truth.
