Method of preservations of the Quran after the demise of the Prophet

It is an incontrovertible historical truth that the text of the Holy Qur'an extant today is, syllable for syllable, exactly the same as the Holy Prophet (PBUH) had offered to the world as the Word of God. After the demise of the Holy Prophet, the first Caliph Hadhrat Abu Bakr (PBUH) assembled all the Huffaz and the written records of the Holy Qur'an and with their help had the whole text written in Book form. In the time of Hadhrat 'Uthman (PBUH) copies of this original version were made and officially dispatched to the Capitals of the Islamic World. Two Of these copies exist in the world today, one in Istanbul and the other in Tashkent. Whosoever is so inclined may compare any printed text of the Holy Qur'an with those two copies, he shall find no variation. And how can one expect any discrepancy, when there have existed several million Huffaz in every generation since the time of the Holy Prophet (PBUH) and in our own time? Should anyone alter a syllable of the original text of the Qur'an, these Huffaz would at once expose the mistake. In the last century, an Institute of Munich University in Germany collected FORTY-TWO THOUSAND copies of the Holy Qur'an including manuscripts and printed texts produced in each period in the various parts of the Islamic World. Research work was carried out on these texts for half a century, at the end of which the researchers concluded that apart from copying mistakes, there was no discrepancy in the text of these forty-two thousand copies, even though they belonged to the period between the 1st Century Hijra to 14th Century Hijra and had been procured from all parts of the world. This Institute, alas! perished in the bombing attacks on Germany during World War II, but the findings of its research project survived. Another point that must be kept in view is that the word in which the Qur'an was revealed is a living language in our own time. It is still current as the mother tongue of about a hundred million people from Iraq to Morocco. In the non-Arab world too, hundreds of thousands of people study and teach this language.
The grammar of the Arabic language, its lexicon, its phonetic system and its phraseology, have remained intact for fourteen hundred years.
A modern Arabic-speaking person can comprehend the Holy Qur'an with as much proficiency as did the Arabs of fourteen centuries ago. This, then, is an important attribute of Muhammad (PBUH), which is shared by no other Prophet or Leader of Religion. The Book which God revealed to Him for the guidance of mankind is today's in its original language without the slightest alteration in its vocabulary
