It all begins in infancy. Not long after birth, every human being is curious. To know. To learn. To explore. Some of our questions drive our parents nuts. Yet, we keep on asking, and thinking, and making our own conclusions, then rethinking and changing the conclusions already made. Human beings therefore are curious creatures. Whether it is the simple childish desire to know what snow tastes like, or the ultimate question, “Who am I and where do I come from?”, curiosity is an inherent part of what makes us human. The Holy Quran calls those curious people who ponder over the creation of the heavens and the earth, the ulul al-baab (people of understanding). It is a statement of praise. No doubt, from age immemorial, curiosity is what has driven us forward in the fields of science, economics, sociology, psychology, and so on. The religion of Islam is no different. Learning Islam and advancing in spirituality requires curiosity. Being Imams, we have been asked a variety of questions from Muslims and non-Muslims alike over the past several years. In this book, we share our answers to thirty commonly asked questions related to contemporary topics. Let us take you on this journey—this quest—to learn how Islam responds to the challenges of modern society.
