According to Maulana Wahiduddin Khan, Islamic fundamentalism is a recent phenomenon. While studying it we must first understand that the term ‘Islamic fundamentalism’ has not been derived from the Islamic scriptures. Though non-Muslims coined this term, the phenomenon for which the term Islamic fundamentalism is used is indeed a reality. There are a considerable number of Muslims in the world whose thinking and actions add up to what is meant by the term fundamentalism. The present book makes a detailed study of its principles and practices to evaluate the movements spawned by it, which are highly active all over the world under one name or the other. Further, it analyzes this way of thinking and how it can be re-engineered on peaceful lines.
