The Kubrawiya order () or Kubrawi order, also known as "Firdausia Silsila", is a Sufi order that traces its spiritual lineage ("Silsilah") to the Islamic prophet, Muhammad, through Ali, Muhammad's cousin, son-in-law and the First Imam. This is in contrast to most other Sufi orders that trace their lineage to Ali. The Kubrawiya order is named after its 13th-century founder Najm al-Din Kubra, who lived in Konye-Urgench under the Khwarazmian dynasty (present day Turkmenistan). The Mongols captured Konye-Urgench in 1221 and killed much of the population including Sheikh Najmuddin Kubra.
