This book is in two parts with the first part exploring the concept of migration (hijrah), Muslim residence in non-Muslim lands, and the classification of lands. The discussions on traditional classifications of lands reveal the diversity of Islamic legal thought on the subject while elucidating the meanings of Hijrah as found in the Qur'an and Hadith and emphasizing its coexistence with Muslim residence in a broader Islamic legal framework. Shedding light on the multifaceted nature of these issues, this book demonstrates the importance of understanding the historical and jurisprudential context in addressing contemporary challenges faced by Muslim minorities residing in non-Muslim lands.

The second part of the book delves into the complex topics of disbelief (Kufr) and excommunication (Takfir) providing a comprehensive understanding of their definitions, conditions, and the nature of evidence required for their identification in contemporary society. It establishes the criteria for justifying takfir and addresses issues related to the authority to declare takfir. It debunks the common misconceptions and misuses of takfir, offering insights into contemporary issues like working for non-Muslim governments, residing in non-Muslim lands, involvement in interest-based (riba) financial institutions, and many more.

The book underscores the need for caution and precision when dealing with these complex issues while appreciating the richness and depth of Islamic jurisprudence. It thus encourages a thoughtful and considered approach to issues related to governance, residence, disbelief, and excommunication in the contemporary world.
