Is there an original copy of the Koran?

There is an original copy of the Koran in the chest of every Muslim who memorizes it; we see that all Muslims unlike others, they never differ about the chapters of the Koran or its verses or its words or its accents or even its letters. The Koran memorized by an Arab Muslims is the same Koran memorized by an Indian or a Persian or a European or an American or a Russian or any other Muslim. Besides, the authentic copy of the noble Koran collected by our sir Abu-Bakr and put at the house of lady Hafsa daughter of Omar Ibn-Al-Khattab, was taken by our sir Othman and he made four copies and sent them to different parts of the Muslim nation of his time. The copy sent to Egypt is still kept in the Islamic museum at Bab El-Khalk in Cairo and it is called "The Mos-haf of Othman". There is another copy kept in the museum of prophetic remains in Astana in Turkey. They are the authentic copies from which are written and printed all the copies of the Koran until now.
Islam is religion of peace
