If it claims to be Universal, why was Qur’an revealed in Arabic?

I commented the following on an article [If You’re So Trad, Why Don’t You Move to Afghanistan] on Counter-Currents where I share my views under the name ‘Muhammad Aryan’.

The text in bold is parts that I quote from the article.

To which Mr. Vehmgericht replied,

I reply as follows:

So what if it is Arabic??

Linguistic expression rests in the metaphysical domain.

It is one aspect that distinguishes us human beings from other living creatures. It is something above the biological existence.

On the biological grade, we are all divided into different races and tribes.

However, on the metaphysical level, we are all the same.

For instance, how does a Dravidian who speaks Tamil or Malayalam or Kannada, etc., masters the languages of the Indo-European or Afro-Asiatic families?

How does a Korean or Indonesian learn English or French or German and vice versa?

So on and so forth.

A child does not born with a language already saved in his memory. He familiarizes himself with the sounds he hears around him and then tries to express them with his tongue.

What if a child born to German parents grows up in a Spanish household where he never listens to a word of German? Will he speak German? That is why to preserve a culture, it is necessary that children of a given ethnolinguistic community be taught about their ancestral heritage. Otherwise, that heritage will be lost.

There are many non-Whites who speak and write English better than most Englishmen, however, that does NOT mean that English heritage will be preserved even if there are no Whites Anglo-Saxons around.

Immigrants who migrate to Western lands like the UK, USA, Canada, New Zealand, Australia, the Netherlands, Belgium, etc., from South/West Asia faced this disconnect. Many a time, their children cannot speak the language of their ancestors or those who do speak, speak it in alien accents. Indeed, this is a strange breed of men which does not belong anywhere. It hangs in the air. It has no grounding.

Anyhow, coming back to the argument.

Men can learn any language. As we can see, it is quite evident.

There are Muslims of Han, Senegalese, Berber, Kurdish, Indonesian, Caucasian, Tamil, Bengali, Assamese, Turkic etc., stock who when recite the Arabic verses do not give a hint that they belong to an entirely different linguistic family.

Qur’an was revealed in Arabic because learning and mastering a language is embedded in our constitution. It is a universal aspect of human nature.

Hence, if Providence chose Arabic for the transmission of the Final Revelation to mankind, it was perfectly in line with our disposition.
