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).

Classical Sufi scholars have defined Sufism as "a science whose objective is the reparation of the heart and turning it away from all else but God". Alternatively, in the words of the Darqawi Sufi teacher Ahmad ibn Ajiba, "a science through which one can know how to travel into the presence of the Divine, purify one's inner self from filth, and beautify it with a variety of praiseworthy traits".

Classical Sufis were characterised by their attachment to dhikr (a practice of repeating the names of God) and asceticism. Sufism gained adherents among a number of Muslims as a reaction against the worldliness of the early Umayyad Caliphate (661-750 CE). Sufis have spanned several continents and cultures over a millennium, at first expressed through Arabic, then through Persian, Turkish and a dozen other languages. "Orders" (ṭuruq), which are either Sunnī or Shī'ī or mixed in doctrine, trace many of their original precepts from the Islamic Prophet Muhammad through his cousin 'Alī, with the notable exception of the Naqshbandi who trace their origins through the first Caliph, Abu Bakr. Other exclusive schools of Sufism describe themselves as distinctly Sufi. Modern Sufis often perform dhikr after the conclusion of prayers.

Nusrat Fateh Ali Khan (Punjabi: نصرت فتح علی خان (Shahmukhī)) (October 13, 1948 – August 16, 1997), a world-renowned Pakistani musician, was primarily a singer of Qawwali, the devotional music of the Sufis (a mystical tradition within Islam). Considered one of the greatest singers ever recorded, he possessed a six-octave vocal range^{[citation needed]} and could perform at a high level of intensity for several hours. Extending the 600-year old Qawwali tradition of his family, Khan is widely credited with introducing Sufi music to international audiences. He was popularly known as "Shahenshah-e-Qawwali", meaning "The King of Kings of Qawwali".

Born in Faisalabad, Pakistan, Khan had his first public performance at age of 16, at his father's chelum. He officially became the head of the family qawwali party in 1971, and was signed by Oriental Star Agencies (OSA), Birmingham, U.K., in the early 1980s. In subsequent years, Khan released movie scores and albums for various labels in Pakistan, Europe, Japan and the U.S. He engaged in collaborations and experiments with Western artists, becoming a well-known world music artist in the process. He toured extensively, performing in over 40 countries.
