Students would be taught this knowledge in inner religious circles located in private homes and in mosques, hoping to create an atmosphere of refined religious thought that would safeguard the transmission of religious knowledge.

From this the Sufi sheiks would establish a set or rituals and practices that would perpetuate the culture of Sufi learning, based upon the Sunnah.
