Sufism

Sufism or taṣawwuf (Arabic: تصوّف‎) is defined by its adherents as the inner, mystical dimension of Islam. A practitioner of this tradition is generally known as a ṣūfī (صُوفِيّ). Sufis believe they are practicing Ihsan (perfection of worship) as revealed by Gabriel to Muhammad, "Worship and serve Allah as you are seeing Him and while you see Him not yet truly He sees you."
