Khalīl Allāh I (Arabic: خليل الله الاول), known in Nizari Isma'ili tradition by the Sufi name Dhūʾl-Faqār ʿAlī (Arabic: ذو الفقار علي), was the 37th imam of the Qasim-Shahi branch of Nizari Isma'ilism.
[1] Khalil Allah succeeded his father Murad Mirza when the latter died in 1574.
[1] Like his father, he resided in and was buried at Anjudan in central Persia, where his tombstone survives to this day.
He married a princess, possibly a daughter of Shah Abbas I (r. 1588–1629), and in 1627, the Safavid ruler issued an edict exempting the Shi'a of Anjudan from certain taxes.
[2] As Farhad Daftary points out, the edict refers to the Anjudani Shi'a as Twelvers, indicating that Khalil Allah and his followers were hiding their true faith.
