In this work, the world renowned scholar of comparative fiqh, Dr. Saalih al-Sadlaan of Muhammad ibn Saud Islamic University discusses the most important issues of fiqh. In this work, the author has done an excellent job of concisely mentioning the most important aspects of the different fiqh topics he discussed. Furthermore, he has discussed many issues that are not greatly discussed in the English literature, such as the rules concerning bequests and endowments. Hence, this work has chosen to be translated as a welcomed addition to the available English literature. It should be noted that this work was first written with the intention that it would be translated as a basic and introductory work on fiqh for the Islamic republics that formerly formed part of the U.S.S.R. This book is excellent as a textbook for workshops and schools, as well as a primer for new Muslims. There is definitely a need for such books in English. The fundamental, agreed upon points are presented clearly for the teacher and the students. Teachers and Imams may expound on the evidence for the positions that Dr. al-Sadlaan holds and discuss the issues in greater detail. Hence, it may lay the foundation for a much better understanding of the essential topics that Dr. al-Sadlaan has chosen to discuss in this introductory work.
