Sufism has a history dating back over 12 centuries. It began as a peaceful protest movement during the 8th century Umayyad Caliphate addressing elitism and materialism. Sufis honor Muhammad as the prophet and their spiritual practices involve humility, reflection, and finding unity with God. Rumi's writings in the 13th century helped spread Sufi ideals across the Muslim world. Idries Shah, born in the early 20th century to an Afghan father and Scottish mother, wrote over 30 books to introduce Western audiences to Sufism and spread its message of peace.
