Any fundamental religious teaching is based on theses, principles and dogmas, which are, as a rule, set out in the main book of each specific religion. In Islam, such a book is the Holy Quran.

The Koran, or more correctly Qur'an, is translated from Arabic as “edification”, “reading”. In fact, it is believed that this holy book contains the word of God, transmitted in revelation to the Prophet Muhammad (peace and blessings of Allah be upon him!) and put into his mouth. Thus, the Holy Qur'an is a manifestation of the absolute divine principle for Muslims in particular and for people in general.
