How can the code of right conduct prescribed by the Qur'an stand as the proof for it's divinity ?

Man is the only creature who has been facilitated with the ability to act independently in his relation with both nature and society. His actions can prove to be useful and harmful as well. In contrast with the other creatures - who compulsorily follow the laws described by their own genetic code and thereby attain to the object of their life - he is to conform to certain laws and commandments for his very existence and survival. It is certain, therefore, that conformation to these laws leads to his own well being while non-conformance to his own destruction.

Which are these laws and recommendations ? Which are the commandments that would serve to brighten up human life and existence? It was to instruct people in these that the messengers were appointed. They presented before the people the example of their own lives which had been cleansed owing to their conformance with the divine commandments. In addition to this, the scripture that contained the divine commandments were also revealed through them. It was these scriptures and the messengers, who confronted the people with them, who provided a faultless knowledge of good and evil. Messengers of God have been sent all places of human habitation in the world. It is, therefore, that the foundations of the moral code prevalent in different nations of the world are one and the same.

Arrogance is the most despicable of satanic traits. It is from arrogance that selfishness, too, finds its origins. Man is eminently capable of so transforming everything that surrounds him in such fashion that it suits his own interests. Indeed, nothing - not even the things material and spiritual - is free  from this influence. In the case of the religious scriptures, too, this has been the end result. The prophets interpreted the scripture according to divine revelations. Their successors ought to have followed them loyally. However,  priests and other men of religion, who appeared in the guise of loyalists in later years injected into the religious texts, as well as the practices taught by the messengers, accretions which were of their own making and which also helped to serve their own selfish interests. They, thus, rewrote the religious laws and perverted the tradition of the prophets to serve their own interests. It, thus, became difficult to follow the dictates of the religious texts. The messengers were shown not as role models who were to be emulated. For this reason, today, we feel the laws and commandments described in the books that come with a religious covering, to be impracticable.

A code of law that will serve to civilise and to purify the minds of men and which is practicable as well, can only be formulated by divine guidance . It is here that all materialistic ideologies fail. They appear on the scene with solutions seemingly for all the travails of mankind. Furthermore, their recommendation will appear, more often that not, to be perfect on paper. However, when tested at a practical level they end up being mere idiosyncrasies. The fact that is thus highlighted here is that it is only the Creator of man himself who is able to provide  a legislation that will serve to cleanse him and be practicable as well.

It is because of this limitation that communism, which was seen as the hope of the twentieth century, was forced to retire into the dust - bin of ideologies by the last decade of that century itself. Those who seek to learn the lesson that emanates from this fall will do well to appreciate the fact that no matter how strong the theoretical foundations on which they are based, no philosophy of materialism can ever hope to provide  the lasting provision of guidance that may effectively cleanse mankind.

Besides this, there is another reality that may also come in for appreciation. This is the fact that the book which does provide for a wholly practicable legislation and also cleanses humanity as well will be divine in itself. This is why it is said that the provision of guidance of the Holy Qur'an constitute the very proof of its divine nature. There is no difference of opinion over the fact that the legislations put forward by the Qur'an does, indeed, serve to make men morally conscious and righteous individuals. This is a reality that has been admitted even by die-hard materialists as well. It has been recognized by impartial observers who have studied the subject that if the obligation of a religious scripture is the guidance of humanity then there can be no book that deserves to be called a religious scripture like the Qur'an.
