I was discussing with a Christian friend of mine the authenticity of the Holy Qur'an, and I explained to him that without a shadow of a doubt that the Qur'an has been maintained word for word since it was delivered to us by the Prophet Muhammad (PBUH).

So he replied to me, that "assuming the Qur'an is authentic, how do we know that the meaning of the Arabic words and language hasn't changed?"

I got stuck. I am aware that it would be difficult to change due to the context clues of the most common words, but I wasn't able to give him a good answer?

I am even aware that are debates of meaning of specific verses such as in Surat At-Tariq [86:7]

Emerging from between the backbone and the ribs.

As opposed to the other translation that says:

Emerging from between the backbone and the loin.

The explanations of the language are written in the language, how could I have explained to him how we know that the language as a whole hasn't changed? Thanks.

EDIT: I must clarify that I am well aware that spoken Arabic has changed in meaning, my question is in reference to word by word meaning of the Qur'anic Arabic.

You see, the problem here is that the Arabic language has changed. Which can be said for pretty much any other language that has been in use for over fourteen centuries. Arabic, as it is commonly spoken and understood around the world, really has little in common with the Arabic spoken during the time of the Prophet and encoded in the Qur'an.

Heck, even the Arabic language at the time had multiple dialects and the Qur'an itself has multiple variant readings which are all considered canon.

As Muslims, where we put our ultimate faith is important, and it is common especially in such interfaith debates for ones faith to end up misplaced: Are we putting our faith in language, the vagaries of which can change over hundreds of years? Are we putting our faith in ink and paper, which is fragile and recorded by imperfect men? Or are we putting our faith in Allah Al-Hadi Ar-Rashid, who can protect His message and guide us to the right path no matter what?

  • I must clarify I meant Quranic Arabic in my question. I'm well aware that the dialect of modern Arabic has changed. And while faith is important, our religion is built off of logic and reasoning. I was asking the for the scholarly reason that our language has maintained meaning. Jul 24, 2020 at 20:42
  • @Youseflapod You say "Quranic Arabic" as if it's just one thing that everyone actually agrees on. There are multiple different readings of the Qur'an, all of which have significant variations in writing and word use.

I somewhat disagree with the answer given ln by @goldpseudo.

The Arabic language - restricted on the words of the qur'an- has not changed. But similarly as the restriction made by 'Othman ibn' Affan in his compilation of the qur'an by favoring the language of Quraish. The - in use- language has restricted certain meanings. And mainly killed the diversity of the language. Nevertheless in some Arabic dialects older meanings still exist and are applied until today. But people who are not familiar with these meanings and words may consider these dialects as strange. This is due to the fact that Arabic speakers now in practice don't speak or use the standard Arabic or the Arabic of the qur'an anymore in most if not all their daily life.

This is the main reason why many native Arabic speakers may have issues understanding the qur'an. As the language they practice is far away from it if may only know one meaning out of many other different meanings. For example the word:


In classical Arabic doesn't refer only to whale, but to fish in general too. The later meaning is only used in certain dialects of North Africa by now while all other Arabs laugh when they hear people inviting them to eat الحوت and then they only find what they know as:


  • I'm sorry I meant in reference to "how do we know the meaning of the Arabic in the Qur'an hasn't changed, as in how do we know that the word الحوت means fish in classical Arabic and not something else? Jul 24, 2020 at 20:45

    @Youseflapod How do you know anything? Because otherwise it doesn't make sense. We have tafasir, writings, and narrations about the Quran since it was revealed. The other option is that Arabic suddenly changed after Muhammad (SAW) died and before the tafasir started getting written. The first option makes sense, and the second doesn't.
