Religious Reasons Holy books of religions are written in the alphabets of the languages used in the countries the
religions originated from. Koran is a good example of this case. Nations other than the Arabs, such
as Selçuks, Turks and Iranians who want to read the Koran decided to adopt the Arabic alphabet.
However, when they realized that the Arabic alphabet is not fully suitable for their languages, they
had to modify it and added some new letters and symbols.
Several North African nations also changed their languages and now they are speaking Arabic
even though they are not ethnically of Arab origin.
