Uniqueness of the Quran

The study and knowledge of the Qur'an is essential for every learned person as well as for all faithful believers. A brief glance over history would be enough to provide sufficient proof of the claim that there has been no such book that has ever influenced human societies to the magnitude of the Qur'an. It is for the same reason that the Qur'an automatically steps into the precincts of sociological discussions, and becomes the elemental constituent of the subjects of research in this discipline. This means that any deep study and profound research in the field of world history of the last fourteen hundred years, is impossible without the knowledge of the Qur'an.
The study of the Qur'an is essential for every committed Muslim, since it is the main source and foundation of the religious thought and faith. Whatsoever gives meaning, essence and sanctity to his existence lies in the Holy Qur'an. The Qur'an is not just like other religious books which are content to discuss the problems of existence of God and creation in cryptic tones, or like those which merely convey a series of simple moral advice and counsels, so that those who believe in them are hopelessly left to search for guidance in other sources. Unlike such books the Qur'an formulates the tenets of faith besides communicating the ideas and views that are essential for a man of faith and belief. Similarly, it also lays down the principles of moral and ethical values for the purpose of social and familial existence. It leaves the job of explanation, interpretation, and occasionally that of ijtihad and application of principles (usul) to secondary matters (furu') to be dealt with through ijtihad and sunnah. Accordingly, utilization of any other source depends on the prior knowledge of the Qur'an. The Qur'an is the criterion and standard for judging all other sources. We should judge hadith and sunnah in the light of the Qur'an. We can accept it only when it is in accordance with the Qur'an, otherwise we do not accept it.
