Investigating Intrinsic Duality of Law and Spirit: An Analysis of Abū Yazīd’s Sufism

The intricate relationship between the duality of outward (ẓāhir) and inward (bātin) religiosity has expressed significant attention concerning contemporary scholars. This dynamic interplay of intrinsic spiritual realization offers a significant religious identity, which cannot stand alone. Such inquiries within the Islamic tradition, are expressed through the duality of terms such as “Sharīʻa and Ṭariqa,” “law and spirit,” or “fiqh and taṣawwuf.” The issue has remained highly contested throughout the history of Islamic thought. The idea that there are two categories of scholars—those who belong to the outward (ʻulamā' al-ẓāhir) and those who belong to the inward (ʻulamā' al-bāṭin)—are known in the intellectual and spiritual culture of Islam. For Sufis, the spiritual dimension constitutes the core of the Islamic perception of a well-rounded personality and maintaining the balance between both the internal and external aspects of human actions, ritual or otherwise, is foundational for realizing the Islamic ideals in life. Despite this, misunderstandings continue to surface in scholarly writings. Thus, this paper attempts to address this issue of outward and inward religiosity through the perspective of the pioneer of the Sufi movement in Islam, Abū Yazīd al-Bisṭāmī (d. 234/878), who was termed by al-Junayd as “Gabriel among the angels.” Additionally, this study aims to elaborate on the original Sufi position through al-Bisṭāmī and contribute to the contemporary awakening towards the spiritual value of human life.
