The hurûfî movement, emerged in Iran in the second half of the14th century, is part of the «heterodox» trends whose doctrines are situated at the edge of the mainstream Islam. In spite of its significant historical role, the doctrine of this movement is still little known. This is partly due to the cryptic character of the Jâwdân-nâma, foundational text of the Hurufism, which is still unpublished. In particular, the passages related to each specific subject are divided and scattered throughout differents places of the text. In our dissertation, we make an attempt to solve the problem of fragmentation and to obtain a coherent presentation of the do trines contained in the Jâwdân-nâma, as a first step towards the reconstruction of the origial hurûfî doctrine.
