In every matter, be it personal, familial, societal or national, we have a tendency to nitpick its negative aspects while ignoring the positives. Some people, while blindly ignoring the beauty of Islam, put considerable hard work into focusing attention on the minor theoretical figh-related differences of opinion and spreading the stench of discord in society. The main causes of this are ignorance and an extremist way of thinking. Only Allah's blessing and unbiased research can cure this disease. If we knew the simple and truthful discussion of the science of fiqh, we would never go into the extremes of either blind-following or abandoning madhabs. We want to drive away the fog of ignorance that has enveloped the society, using the pure gust of knowledge. This book is a part of this plan for the revival of knowledge. It is a must-read for every Bengali Muslim, especially due to its historical setting.
