Islam's Holy book and guidance to mankind. It is the final revelation of the will of Almighty God's to all of mankind, which was conveyed through the Angel Gabriel, in Arabic, to the Prophet Muhammad in its sounds, words and meanings. The Qur'an, sometimes spelled Koran, was relayed to the Prophet's companions, which they memorized verbatim, and which has been publicly and continually recited by them and their successors until the present day. In short, the Qur'an is the book of guidance from God par excellence. The Qur'an is still memorized and taught by millions of people. The language of the Qur'an, Arabic, is still a living language to millions of people, so unlike the scriptures of other religions, the Qur'an is still read in its original language by countless millions of people. The Qu'ran is a living miracle in the Arabic language; and is know to be inimitable in its style, form and spiritual impact. God's final revelation to mankind, the Qur'an, was revealed to the Prophet Muhammad over a period of 23 years. The Qur'an, in contrast to many other religious books, was always thought to be the Word of God by those who believed in it, i.e. it wasn't something decreed by a religious council many years after being written. Also, the Qu'ran was recited publicly in front of both the Muslim and non-Muslim communities during the life of the Prophet Muhammad. The entire Qur'an was also completely written down in lifetime of the Prophet, and numerous companions of the Prophet memorized the entire Qur'an word-for-word as it was revealed. So unlike other scriptures, the Qur'an was always in the hands of the common believers, it was always thought to be God's word and, due to wide-spread memorization, it was perfectly preserved. In regards to the teachings of the Qur'an - it is a universal scripture, and it is addressed to all of mankind, and not to a particular tribe or "chosen people". The message that it brings is nothing new, but the same message of all of the prophets - submit to Almighty God and worship Him alone. As such, God's revelation in the Qur'an focuses on teaching human beings the importance of believing in the Unity of God and framing their lives around the guidance which He has sent. Additionally, the Qur'an contains the stories of the previous prophets, such as Abraham, Noah, Moses and Jesus; as well as many commands and prohibitions from God. In modern times in which so many people are caught up in doubt, spiritual despair and "political correctness", the Qur'anic teachings offer solutions to the emptiness of our lives and the turmoil that is gripping the world today.
