The Nasuhi are a sub-order of the Khalwati Sufi order. Their founder, Pir Nasuhi, was a prolific author who wrote a number of works, including a commentary upon the Qur'an. He died and was buried at his Özbekler Tekkesi in Üsküdar, Istanbul. The order was not a widespread order and had only a number of tekkes in Istanbul and Bursa.
