Tablighi Jamaat-A faith renewal movement, founded in the 1920s by Maulana Mohamad Ilyas in Mewat, India, has emerged today as the most prominent transnational religious movement throughout the Muslim world. Its influence and success have been reported from over 180 countries, including North Africa, South Africa, Pakistan, Bangladesh, as well as among Muslim immigrants in the western European countries (like Germany, France, Switzerland), Eastern Europe (Denmark, UK), Canada, United States, and Australia. This is primarily because of its unique ideology and organisational features like its apolitical nature, focusing on touring, travelling or patrolling, showing aversion to publicity and perceiving dawah (preaching or invitation towards Islam) as the fundamental obligation of each and every Muslim enjoined by Quran. Against this backdrop, this book provides a simple and lucid description of Tablighi Jamaat, its ideology and organisational structure.
