For the first time in Russian, a translation from Arabic of the main works of one of the most mysterious figures in the history of Sufism of the 10th century Arab mystic Muhammad bin 'Abd al-Jabb? ra al-Niffar?. The peculiarity of Niffar's legacy, which turned him into a marginal figure, is that practically weight texts (including those attributed to him) are built in the form of dialogues between God and the adept, which explain the most important concepts for Sufism and generally significant for Islam. The lack of references, the very bizarre logic of thought and presentation turn reading these texts into a kind of training to expand the boundaries of the reader's consciousness and deepen his understanding of the limited possibilities of human nature in comprehending Divine reality.
