Studies In Tasawwuf (1923) – Khan Sahib Khaja Khan

“Studies In Tasawwuf” (1923) by Khan Sahib Khaja Khan is an important early 20th-century English language work that aims to systematically introduce and explain the esoteric side of Islam, or Sufism, to a wider readership, particularly those unfamiliar with Urdu and Persian sources. Through a collection of essays, the book delves into complex topics like the nature of Dhat and Sifat (Essence and Attributes of God), Insan-ul-Kamil (The Perfect Man), Fana and Baqa (Annihilation and Subsistence), and the philosophic schools of Islamic thought. Khaja Khan argues that without this spiritual, esoteric dimension, Islam is reduced to a “mere skeleton of formalities.”
