Tasawwuf (Sufism): A Historical Overview

Tasawwuf (often rendered Sufism in English) is the science and practice of Islamic spirituality most closely associated with ihsan — the third dimension of religion named in the famous Hadith of Jibril, alongside Islam (outward practice) and Iman (belief). Asked what ihsan means, the Prophet answered: “What is al-Ihsan? Upon this he said: that you fear Allah as if you are seeing Him, and though you see Him not, verily He is seeing you” (Sahih Muslim, 99). Many scholars across history, of varying theological and legal schools, have understood tasawwuf as the disciplined cultivation of this state — sincerity, God-consciousness and closeness to Allah in worship — building directly on the same ground as the Tazkiyah lesson on this page.

As an identifiable movement, tasawwuf’s roots are usually traced to early ascetic (zuhd) tendencies among some of the Companions and the generations after them, emphasising simplicity and detachment from worldly life. It developed into a more structured discipline over the following centuries, with figures such as Al-Junayd of Baghdad (d. 298 AH / 910 CE) associated with its early systematic articulation, and Abu Hamid al-Ghazali (d. 505 AH / 1111 CE) particularly influential in integrating it with mainstream Sunni theology and law in his later writing. From roughly this period onward, tasawwuf increasingly organised into tariqahs (orders) — structured chains of teachers and students, such as the Qadiriyyah, Naqshbandiyyah and Chishtiyyah among many others — each with its own transmitted practices and emphases.

Scholarly assessment of tasawwuf spans a genuine range, and this page does not take a side in it. Many Sunni scholars across the centuries, including a number associated with the Ash’ari and Maturidi schools and some Hanbali and Athari scholars, engaged with and affirmed core Sufi spiritual practice as a legitimate expression of ihsan, while distinguishing it from what they regarded as later excesses. Other scholars, including prominent voices within Athari-aligned and reformist currents, have been critical of specific historical developments associated with some Sufi orders — certain practices around venerating graves or intermediaries, and some metaphysical claims made by particular later figures — while not necessarily rejecting the concept of tasawwuf or ihsan itself. The disagreement, where it exists, is generally about specific historical practices and claims, not about whether sincerity, humility and closeness to Allah in worship matter.

This is presented here as intellectual and spiritual history, not a guide to any particular tariqah or a recommendation to join one. Readers interested in the practical, agreed-upon core of this territory — sincerity, guarding the heart against pride and showing off, remembrance of Allah — are better served by the Tazkiyah lesson on this page and the Duas & Adhkar Centre than by this historical overview.
