Sufi philosophy includes the schools of thought unique to Sufism, the mystical tradition within Islam, also termed as Tasawwuf or Faqr according to its adherents. Sufism and its philosophical tradition may be associated with both Sunni and Shia branches of Islam. It has been suggested that Sufi thought emerged from the Middle East in the eighth century CE, but adherents are now found around the world.

Nafs (نَفْس) is an Arabic word occurring in the Quran, literally meaning "self", and has been translated as "psyche", "ego" or "soul". The term is cognate with the Hebrew word nephesh, נֶפֶשׁ. In the Quran, the word nafs is used in both the individualistic and collective sense, indicating that although humanity is united in possessing the positive qualities of a nafs, they are individually responsible for exercising the agencies of the "free will" that it provides them.
