Synopsis Presents a comparative study of Islam with respect to the other existing religions of the world. The book has been translated in English in order to promote the understanding of Islam by all, especially the non-Muslims in the West. The author has researched and reported the basic principles of the religions with great reverence. He also responded to the objections raised by the non-Muslim critics about Oneness of God, finality of Divine revelations to mankind and the institution of messengership on the Holy Prophet.  The author has aptly explained the Principles of Jihad. It means the struggle to suppress the evil and to promote 'good', within as well as without oneself. It does not deprive people of their freedom nor it means to acquire wealth. Further, this book shows the Qur'anic truths in face of the scientific postulates which, are themselves, ever-changing. It reasons out some natural phenomena as compatible with the statement of the Qur'anic Scriptures.
