Yes. The Qur'an is, indeed, a book that is practicable in all respects. In fact, there is but one, and only one, book that exists today which fulfills the goal of divine scripture, namely, to unite all mankind by guiding it along the path of truth and morality. That is the Qur'an. The moral laws which it propounds are completely practicable. The fact remains, therefore, that it is the Qur'an alone which provides for the formulation of a social code that is based on ethics and morality.
