'Dr. Palmer’s thoughtful and well documented examination of the rise and development of the concept of “sainthood” in ascetic-mystical Islam is intimately relevant to the ongoing intellectual and theological debates in the Muslim world and in Muslim diaspora communities over normative notions of Islamic doctrine and practice.'
Alexander Knysh, Professor of Islamic Studies, University of Michigan, Ann Arbor

‘[...] the book makes an interesting and rewarding read on the whole not only on account of its lucid style and well-knit arguments but also for many original insights that the students and scholars of Islamic history would find illuminating and instructive.’
The Muslim World Book Review, 42:4, 2022 (42-44).
