The original copy is lost but there is a microfilm record at Suleymaniye Manuscript Library. Apart from a few book reviews, this work has still not attained enough attention from researchers. In this article, we examine a section on music in Safina al-Safi. This chapter is about the oud and its history, its process of making, and the fifth string that is added to oud later. When examining the subjects and the way that Ahmad Safi dealt with in his work, it has been seen that he made quotations from some works. There are some mistakes in the information given, both historically and theoretically. We have discussed these issues in turn with the following and have subject to some criticism. Some of the incomplete and incorrect information contained in the previous works together with a number of different topics are found because of the historical importance.
