In this book, originally titled Īmān Aur Kufr Qur’ān Kī Roshnī Mein (Īmān and Kufr in Light of the Qur’ān), Muftī Muḥammad Shafī‘* provides a detailed explanation of the principles of Takfīr (declaring someone outside the fold of Islām). As he explains in the preface to the book, most of the academic content is taken from a highly technical and largely inaccessible work by his teacher, ‘Allāmah Anwar Shāh al-Kashmīrī, called Ikfār al-Mulḥidīn. Thus, writing for the benefit of a more popular audience, Muftī Muḥammad Shafī‘ offers a clear understanding of what constitutes Īmān and Kufr, and outlines the principles on which a person who claims to be Muslim while denying core elements of Islām will be deemed a Kāfir.
Since the work was written shortly after the creation of Pakistan, Mufti Muḥammad Shafī‘ also includes a short tangential discussion on the two-nation theory (which was the basis for the creation of Pakistan).
In light of Zandaqah (crypto-Kufr) and Ilḥād (heretical distortion) – concepts discussed in detail in the book – being on the rise today, Muftī Shafī‘’s work is all the more relevant and important.
