Qadiriyyah, one of the oldest Sufi tariqa, derives its name from Abd al-Qadir al-Djilani (1077-1166), a native of the Iranian province of Gilan. In 1134 he was made principal of a Hanbalite school in Baghdad.
The Qadiriyyah has not developed any distinctive doctrines or teachings outside of mainstream Islam. They believe in the fundamental principles of Islam, but interpreted through mystical experience.
