This book is in its original form entiteld Fiqh of Disaster (The Islamic Guiding Principles on Natural Disaster). The term fiqh here means not solely about concrete ruling, but it also covers aspects of theology (aqidah), law (shariah) and morality (akhlaq). Thus, the term fiqh has a broader meaning, encompassing not just the legal aspects, which have tended to be more widely accepted, but as it is used within the tradition of the fatwa and Islamic Research Council of Muhammadiyah, the term fiqh is generally meant as a set of Islamic rules classified into three levels: first, basic values (al-qiyam al-asasiyyah); second, general principles (al-ushul al-kulliyah) and third, the concrete rule of law (al-ahkam al-far'iyyah). The collective intellectual endeavor (ijtihad) that has been undertaken by the Council thus far is aimed at exploring those three things. Based on those broad interpretations of fiqh, we expect this book to provide knowledge and understanding for Muslims on all matters relating to disaster from religious aspects. This book contains the concept of thinking about disaster that includes the true concept of viewing and responding to disaster and to actions that should be done during the disaster
