This guidebook is a short commentary on a work on arithmetic entitled <em>al-Wasīla </em>(The tool) completed in the 14th century by Shihāb al-Dīn Ahmad ibn Alī ibn Imād. The commentary is by the renowned Egyptian scholar known as Sibt (grandson of) al-Māridīnī (1423–1506), who taught mathematical sciences at Alazhar for a long time. The body of the work begins with a general discussion on numbers, and forms a standard introduction to arithmetic. The manuscript, which was completed by Ahmad ibn Yūnus al-Chalabī al-Hanafī in 1496 (AH 903) at the Madrasa al-Ashrafiya, was at some point donated as a <em>waqf</em> (pious gift or bequest) to a mosque.
