Mr. inJESUS,
The preservation of
The Koran was not just through written record but through WORD by WORD complete
memorization in the dialect it was revealed and in the dialects it was allowed to recite and then through continuous remembrance/recitiations in the daily non-stop five times a day prayers and once every year rehearsing of whole text of the Koran during the months of Ramadhan, out of memory and verification by the listeners, right after the Koran was revealed.
The tradition of memorization of the Koran is UNIQUE and there is no such tradition attached to any other religious or non-religious book on the face of this earth in the entire known-history of the world. This Unique memorization is a **
TAWATUR ** tradition which goes back to the Period of Prophet Muhammed (pbuh) from our day.
At the present there are millions of
Huffaaz in the world of Muslims, who knew the whole text of the Koran by heart, word by word. There are numerous
Tafaasir (Commentries) too as well where in the whole text of the Koran is found.
It is only the Arabic original trext which is considered/accepted as
the Koran and it is this text only which is memorized word by word.
If every written document of the Koran (Masaahif) is destroyed from the face of the earth, it is not going to change an iota of the original Arabic text of the Koran because it will be re-written, re-produced, out of memory from the hearts of those millions of Huffaz at any time and in any given period.
More Muslims live in Indonesia now in all Arab countries combined. There are more Huffaz of the Koran in India/Pakistan/Bangladesh/Indonesia/Malaysia than any Arab country.
What the Third Caliph after the Prophet,
Uthmaan ibn 'Affaan, did was, in his period, when Islam spread rapidly in all four directions, and non-Arabs too embraced Islam, they alongwith some Arabs whose dialect/pronunciation was totally different than allowed/revealed dialects of the Koran, were **reciting ** the text of the Koran in other than revealed/allowed dialacts. When this news reached to Caliph Uthmaan, he took a very strong action. Why? Because the Koran was supposed to preserve in it’s pure form as it is since it is considered the last and Final Revelation till the end time of this earth. So he prepared official copies and were verified by the Scribes of the Prophets and Companions of the Prophet and those who knew the whole Koran by heart. There was no objection at that time to the copies made by Uthmaan. Then they were sent to different centers of Islamic Caliphate with an order to retain this original dialect/script and discard every other copy which contradicts.
The one way to retain this Original was to completly discard those copies which might create confusion. Now, were they all destroyed? Not necessarily. Some still might had in their possession who did not hear the order of Uthmaan. But what happened later? Caliphate was turned into Mulukiyyah (Monarchy) after fourth Caliph and a brief period of 'Umar bin Abdul-'Azeez. Many dynesties emerged. Some were shia or pro- Shia too. Some were not fully Islamic. But did they ever try or were able to change the text of the Koran?
