The religious activities of the Chechen Sufi Kunta-Haji Kishiev are revealed. Kunta-Haji expressed his views orally, he sermonized for his followers, demonstrating the practice of performing the ritual associated with the Qadiriyah Tariqa. In Chechnya he became the founder of the Qadiriyah Tariqa. In writing, the teachings of Kunta-Haji are recorded in several arabographic texts which were published in the tsarist period at the beginning of the 20th century in private printing houses in Dagestan. These works were rare, that limited the possibilities of their wide analysis and involvement in scientific circulation. Only in the late 90s of the 20th century, they began to be published in Arabic and Chechen, that allowed to use them wider, assessing the substantive aspects of the teachings of Kunta-Haji. Ideas calling for peace, condemnation of war, violence, cleansing of sins, spiritual perfection, and the search for a path leading to God are valuable in his teaching.
