The Book that God gave to Prophet Mohammad through revelation, and which he passed on to the Muslims in the form in which we know it today. The internal evidence provided by the Quran itself, as well as historical research, proves beyond a shadow of doubt that not even a comma of the original Quranic text has been changed or is likely to be altered in the future. This is a unique attribute of the Quran and is not shared by any other revealed book now extant. The Quran embodies the din revealed to the earlier Prophets in its true and perfect form.

This Book does not give us merely a code of ethics; it provides us with a code of life which embodies guidance, principles and laws relating to every sphere of human life and activity. The Quran, according to Islam, is the final authority in matters of din. The injunctions and the principles enshrined in the Book form the corner-stone of the Islamic polity and the limits laid down by it provide the framework within which the laws of the Islamic State may be formulated. These principles, or limits, or framework, are immutable, but the statutes made by the state within these four corners are open to modification and change according to the needs of the times.

The Quran is the last of the Divine Books, because prophet hood ended with Prophet Muhammad. No subsequent human opinion or pronouncement in matters of din, therefore, can be recognized as authoritative; nor can any man-made law repugnant to the Quran be regarded as binding upon the Muslims. The Quran is a book of guidance for all mankind and transcends the barriers of time and space. The Islamic State is an instrument for the enforcement of the laws and injunctions embodied in the Quran.
