Sufism, or Tasawwuf, has played a pivotal role in Islamic spirituality across centuries. While its core intention—spiritual purification and nearness to God—is universally accepted, its methods, practices, and philosophical underpinnings have varied widely among scholars. Two of the most significant figures in Islamic intellectual history, Imam Abu Hamid al-Ghazali (d. 1111 CE) and Shaykh al-Islam Ibn Taymiyyah (d. 1328 CE), both engaged with Sufism in distinct ways. While al-Ghazali is often celebrated as a bridge between Sufism and orthodox Sunni theology, Ibn Taymiyyah offered a critical reformist approach that sought to align Sufism strictly with the Qur'an and Sunnah. In light of their methodologies and theological commitments, one could argue that the Sufism of Ibn Taymiyyah is more “Sunnatic”—that is, more grounded in the Prophetic model—than that of al-Ghazali.
Al-Ghazali’s Embrace of Sufism
Al-Ghazali, a towering figure in the Ash‘ari theological tradition and a master of Shafi‘i jurisprudence, famously underwent a spiritual crisis that led him to embrace Sufism. In his magnum opus, Ihya’ ‘Ulum al-Din (The Revival of the Religious Sciences), he synthesized Sufi ethics with Islamic law and theology. He emphasized concepts such as intention (niyyah), sincerity (ikhlas), asceticism (zuhd), and divine love (mahabba). These became central to his model of spiritual reform.
However, al-Ghazali’s approach was heavily influenced by philosophical and Neoplatonic ideas. His engagement with ‘ilm al-kashf (unveiled knowledge), his acceptance of metaphysical hierarchies, and his emphasis on inner spiritual states occasionally led him to blur the lines between Sunnah-based worship and esoteric experience. While he criticized certain deviant practices of Sufis, he nonetheless embraced a number of practices that lacked clear Prophetic precedent, such as extended spiritual retreats (khalwa), structured dhikr circles with rhythmic chanting, and discussions of mystical union.
Al-Ghazali’s goal was to purify the soul, but in doing so, he opened the door to speculative Sufism, which, though influential, diverged from the rigorous scripturalism that defines Sunni orthodoxy. As a result, his Sufism, though deeply ethical and transformative, allowed theoretical mysticism and subjective experience a significant role in religious life—often without the same level of scrutiny applied to beliefs and practices in the Qur’an and Sunnah.
Ibn Taymiyyah’s Reformist Sufism
In contrast, Ibn Taymiyyah approached Sufism as a scripturally grounded discipline. He did not reject Sufism outright, as is often mistakenly believed, but distinguished between the Sufism of the early pious generations (al-Salaf al-Salih) and what he saw as later deviations influenced by Greek philosophy, Neoplatonism, and Hindu metaphysics.
Ibn Taymiyyah praised early ascetics like Hasan al-Basri, Fudayl ibn ‘Iyad, and Junayd al-Baghdadi, viewing them as embodiments of sincere worship and ethical conduct. His primary concern was that Sufism should remain tethered to the Qur’an and Sunnah, avoiding speculative metaphysics and unauthorized rituals. He strongly criticized doctrines like wahdat al-wujūd (unity of being), associated with Ibn ‘Arabi, and considered them incompatible with tawḥīd.
In his work Majmu‘ al-Fatawa, Ibn Taymiyyah stated:
“Many of the Sufi shaykhs are from among the people of truthfulness, asceticism, and striving... but among them are those who went astray due to lack of knowledge, and among them are those who innovated in religion. The way of the earliest Sufis is the correct one.”
This encapsulates his vision: affirm the ethical and spiritual goals of Sufism, but only through legitimate prophetic means. For Ibn Taymiyyah, true spiritual realization is not found in altered states or metaphysical speculation but in the correct performance of deeds rooted in divine guidance.
Scriptural Anchoring vs Philosophical Abstraction
The core difference between the two thinkers lies in epistemology—how they determine religious truth. Al-Ghazali allowed for spiritual intuition (dhawq) and unveiled knowledge to play a significant role in guiding the believer. While he also upheld the authority of the Qur’an and Sunnah, his openness to inner experience as a source of knowledge paved the way for later Sufis to adopt non-canonical teachings.
By contrast, Ibn Taymiyyah restricted religious knowledge to wahy (revelation) and the consensus of the early Muslim community. He believed that subjective spiritual experiences, while potentially beneficial, must always be judged by external criteria: the Book and the Sunnah. This methodology reflects the usuli (principled) nature of Sunni Islam, where divine legislation cannot be replaced or superseded by mystical insight.
Therefore, Ibn Taymiyyah’s Sufism is arguably more Sunnatic because it insists that every element of spiritual practice be authenticated by the Qur’an, the Sunnah, and the understanding of the Salaf. This is in stark contrast to models that permit greater latitude for personal inspiration or spiritual experimentation.
On Bid‘ah and Innovation
A major theme in Ibn Taymiyyah’s critique of later Sufism was bid‘ah (innovation). He held that adding to the religion—no matter how well-intentioned—was ultimately harmful. Thus, organized dhikr sessions with singing, dancing, or invented formulas were, for him, forms of deviance, even if they brought emotional satisfaction.
Al-Ghazali, on the other hand, permitted and sometimes encouraged practices that had no clear precedent in the actions of the Prophet Muhammad ﷺ. His defense of such acts was often rooted in maslaha (public benefit) or spiritual utility, but from a Sunnatic perspective, this can be a slippery slope.
In Ibn Taymiyyah’s framework, no spiritual benefit justifies departing from the Prophetic model. His approach safeguards against the proliferation of practices that, while appearing pious, may lead to doctrinal or ritual excesses.
The Practical Consequences
The divergence between Ibn Taymiyyah and al-Ghazali has significant consequences for contemporary Islamic practice. In many parts of the Muslim world, Sufism as practiced today owes more to al-Ghazali’s synthesis than to Ibn Taymiyyah’s rigor. While this has contributed to rich cultural and spiritual traditions, it has also given rise to quasi-superstitious practices, saint veneration, and ritual innovations.
The Taymiyyan model, by contrast, provides a framework that is more resistant to deviation, as it continuously subjects personal spiritual experience to objective, revealed standards. This model is arguably better suited to preserving tawḥīd, avoiding ghuluw (exaggeration), and maintaining theological consistency across time and place.
Conclusion
Both Ibn Taymiyyah and al-Ghazali sought to revive the spiritual core of Islam, but their methodologies and epistemological commitments diverged significantly. While al-Ghazali contributed immensely to the moral and intellectual defense of Sufism, his model allowed room for philosophical abstraction and mystical speculation.
Ibn Taymiyyah, in contrast, pursued a Sufism that was fully submissive to the authority of revelation, rooting spiritual progress in obedience, sincerity, and Sunnah-based worship. For this reason, one can persuasively argue that Ibn Taymiyyah’s Sufism is more “Sunnatic”—more in line with the prophetic model and the understanding of the early generations—than the Sufism of al-Ghazali.
