"At a time when Shiite Islam is a major religious and ideological force in the Middle East, this book constitutes a very important addition to the scholarly literature on this subject. [It] is outstanding in its presentation and analysis of a wide-ranging array of sources, both primary and secondary. It is especially strong in the number and nature of the Arabic and Persian sources comprising religious treatises, Hadith compilations and biographical dictionaries ( Rijal books) pre-modern and modern. One of the best books on Shiite thought that I have read recently or, for that matter, at any time." William F. Tucker, University of Arkansas, author of Mahdis and Millenarians: Shiite Extremists in Early Muslim Iraq , Cambridge University Press, 2008. "Omid Ghaemmaghami's thoroughly researched monograph . offers a well-documented and well-argued historical contextualization of a central idea in Twelver Shiism.

The strength of the book is that it combines thorough philological groundwork with broad historical contextualization.Encountering the Hidden Imam is a well-researched and a thoroughly argued contribution to the religious and intellectual history of pre-modern Islam: it explores both the big picture of political and social change and the detailed small picture of the texts where this change is reflected." Mushegh Asatryan, University of Calgary in: Bulletin of the School of Oriental and African Studies , Volume 84, Issue 1(2021). "Ghaemmaghami has produced a well-researched, well-argued, and clearly written book that fills a gap in the literature on Twelver Shiism." Moojan Momen, Independent researcher in: Religion , Volume 52, Issue 2(2022). "Ghaemmaghami has brilliantly produced an interesting study that will benefit scholarship on Islam, its religious history in general, and the Shiite doctrine of authority in particular. This stimulating scholarly effort is also one more reminder of the importance of a solid, balanced philological approach when dealing with Islamic tradition, piety, and theology." Marco Salati, University of Cà Foscari in: Der Islam , Volume 98, No.

2(2021). ".this work has been written with its readership in mind and provides an important examination of terms, texts and concepts to assist with gaining clarity on this fundamental issue in the Twelver Shi'i tradition." Rebecca Mastertonin, The Islamic College in: Journal of Shi'a Islamic Studies , Volume 12, No. 3-4(2019). "In all, Ghaemmaghami has produced a well-researched, well-argued, and clearly written book that fills a gap in the literature on Twelver Shiism. It is also a useful addition to the literature on 'invented traditions' and the manner in which the 'invented' nature of such traditions is concealed and the traditions consolidated as well-grounded knowledge." Moojan Momen, Independent researcher in: Religion Volume 52 (2022).
