Zakah, the third Pillar of Islam, is probably the first Pillar of its economic system. It represents the first and most important mechanism to implement economic justice and to provide sustenance to the economically unfortunate, two issues for which Islam is especially sensitive. These two issues are the essence of this book. This book consists of all the main issues of Zakat (i-e, Zakah on Gold, Silver, Paper Money, Livestock, Fruits, Grains, Rented Land, Buried treasures, Minerals, Trade, Shares, Stocks, and Exploited Assets etc). The main objective of this work is to serve an easy and authentic reference to the reader.
