Another copy of the work is in the John Rylands Library (A. Mingana, D.D., Catalogue of the Arabic Manuscripts in the John Rylands Library, Manchester 1934, pp. 530, no. 345). That example is dated AH 873/1468 AD. On the basis of the illumination, paper and calligraphy our manuscript can be dated to the 15th century, making it an early copy of the work.
