What should the Christian know about Islam? Islamic Studies, 2^nd Edition (60% more material) prepares students in group, class settings, or privately to know all the essentials of Islam's theology, history, rituals, tendencies, and culture for adequate interaction with Muslims. Knowing the differences between Islam and Christianity is crucial for effective witness. The reader will gain an understanding of what causes radicalization and what ex-Muslims say about the need for reform. Original material included a general outline of Islamic theology, an overview of the Quran, commentary on books by Ayaan Hirsi Ali, Reza Aslan, and Bilal Philips, a short biography of Muhammad's life, an overview of the Hadith and the Sira, other religions related to Islam, an explanation of the Crescent and Star symbol, several opinion essays, and an extensive glossary and bibliography. Additional material in this edition: a condensed study of Sharia Law, both Shia and Sunni versions; a comparison of Islamic and Christian notions of hygiene; "Ultimate Intentions of Islam," "Who Is Gabriel?" "Debating with Muslims;" and "25 Ways to Enter Paradise." This sharply cuts research time for the Christian who is serious about learning about Islam. This is what you need to know in one volume
