The theme of the book is evident from its title: Islam Rediscovered: Discovering Islam from its Original Sources. Its purpose is to present Islam as it is, drawing on its original sources rather than judging it by the later day interpretations and commentaries or the practices of present day Muslims in different parts of the world. In the book Maulana Wahiduddin Khan makes a distinction between Islam as presented by the Prophet Muhammad and his companions (information about which is available to us in the Qur'an and the sunnah) and Islam as represented by later Muslim generations - both in theory and practice. This is what we call the scientific approach. In the book the author explains that Islam is the religion of nature. If it were to be presented in its original form, people would turn to it quite naturally, for example, when a recently converted American by the name of Gary Miller was asked why he had converted to Islam, he replied: “I didn't convert to Islam I have rather reverted to my original religion.” Through the book the author wants to show the religion of Islam, as opposed to the “religion” represented by certain self-styled Muslim leaders introduced to us by the media.
