Najmuddīn-e Kubrā (Persian: نجمالدین کبری) was a 13th-century Persian sufi from Khwarezm and the founder of the Kubrawiya, influential in the Ilkhanate and Timurid dynasty. His method, exemplary of a "golden age" of Sufi metaphysics, was related to the Illuminationism of Shahab al-Din Yahya ibn Habash Suhrawardi as well as to Rumi's Shams Tabrizi. Kubra was born in 540/1145 and died in 618/1221.
Born in 540/1145 in Konye-Urgench, Najmuddin Kubra began his career as a scholar of hadith and kalam. His interest in Sufism began in Egypt where he became a murid of Ruzbihan Baqli, who was an initiate of the Uwaisi. After years of study, he abandoned his exploration of the religious sciences and devoted himself entirely to the sufi way of life.
Sufi sheikh Zia al-Din-'Ammar Bitlisi was Kubra's teacher, who tried to present Sufi thought in a new way to provide contemplation and influence for the reader. After receiving his khirka, Kubra gained a large following of gnostics and writers on Sufism.
Because his followers were predominantly Sufi writers and gnostics, Kubra was given the title "manufacturer of saints" (in Persian: vali tarash) and his order was named the Kubrawiya.
Kubra's main body of works concerns the analysis of the visionary experience. He wrote numerous important works discussing the visionary experience, including a Sufi commentary on the Quran that he was unable to complete due to his death in 618/1221. Kubra died during the Mongol invasion and genocide after refusing to leave his city, where he fought in hand-to-hand combat against the Mongols.
