Prior to the adoption of Islam, the Chechens practiced a unique blend of religious traditions and beliefs. They partook in numerous rites and rituals, many of them pertaining to farming; these included rain rites, a celebration that occurred on the first day of plowing, as well as the Day of the Thunderer Sela and the Day of the Goddess Tusholi. In addition to sparse written record from the Middle Ages, Chechens traditionally remember history through the "illesh", a collection of epic poems and stories.
