This is a significant work on the science of Sufism by Imam al-Sha'rani, in which he sought to dispel from people's minds the misconceptions and superstitions associated with Sufism, thereby restoring it to the pristine purity it possessed during the era of the Pious Predecessors. Furthermore, he addresses the doubts and objections that arose from the differing opinions among scholars in the fields of jurisprudence, theology, and Sufism, while demonstrating that such intellectual diversity constitutes a source of profound scholarly enrichment.
