It is understandable that the author would not assume that Al-Samadi did not draw from other works by Al-Wadi, which he cited in the first part of his book. But what is unknown is the extent of this borrowing, and whether it was extensive or limited. It is impossible for the matter to be otherwise: history is not invented, and it is, for the most part, concerned with previous events that the author continues from other works or from transmitted narratives. It is the right of the author to highlight them and present them in a new form, but it is not permissible for him to change anything of their essence, otherwise he would have to provide conclusive proof for his claims.

From a collection of manuscripts sent by the scholar Arcinar. The manuscript is undated and appears to date back to the "National Library" in Paris, to the late eighteenth century. Humidity had affected the legible part of some of its pages, but it turned out that the illegible parts were nevertheless very few. As for the manuscript, it is from the manuscripts, at the request of Félix de Beau, the author of the book "The Great Journey in Sudan" (1898-1900).

Thus, the two manuscripts stem from the same family or lineage. In 1902, de Beau donated this manuscript to the "National Library". When the Orientalist Houdas was about to finish his research on the book and its translation, the Director of the School of Literature in Algiers, Monsieur Passy, sent him a third manuscript. The history of Sudan, which was sent to him by Dr. Noutan. This manuscript is generally better and more extensive than the other two. Its writing - and it is copied from a different original - and the diacritics accompanying proper nouns are generally taken care of sufficiently, although there are some poorly copied passages and a few words and lines.
