Nizari Quhistani

Hakīm Sa'd-al-Dīn ibn Shams-al-Dīn Nizārī Bīrjandī Quhistānī (Persian: حکیم سعدالدین بن شمس‌الدین نزاری بیرجندی قهستانی), or simply Nizari Ghohestani (died 1320 CE), was a 13th-century Nizari Ismaili author and poet, who lived in the time of the Imam Shams al-Din (Nizari) Muhammad. Nizari was born into a family of landed gentry approximately a decade after the capitulation of the Alamut state and hailed from the town of Birjand. Nizari is the only Ismaili poet of this period whose works are extant. Nizari Quhistani’s work was quoted by many later Ismaili authors, such as the Persian Khwāja Muḥammad Riḍā b. Sulṭān Ḥusayn, also known as Khayrkhvah-i Harati.
