The Holy Book of Allah, the Qur'an, is not the work of a man, nor is it the collected thoughts or opinions of wise men through the ages. It is the "Word of the Almighty God (ALLAH)", the Creator, The Lord of the universe. It is the perfect revelation to mankind. Though called and treated as a book, the Qur'an is not a book in the ordinary sense of the word. It is neither a treatise nor a dissertation on a particular theme; nor it is a book on religion
Just one holy book which is the Noble Quran.
