"The oldest work... complete, on the history of Arabic literature and history is the Kitah al-Fihrist, written in the year 987 a.d., by Ibn Abī Ya'qūb al-Nadīm. ...Of the ten chief divisions of the work, the [second subdivision of the] seventh... treats of mathematicians and astronomers. The first of the Arabic writers mentioned is Al-Kindī (800-870 A.D.), who wrote five books on arithmetic and four books on the use of the Indian method of reckoning. Sened ibn 'Alī... is also given as the author of a work on the Hindu method of reckoning. ...[T]here is a possibility that some of the works ascribed to Sened ibn 'Alī are really works of Al-Khowārazmī ...However, ...Casiri also mentions the same writer as the author of a most celebrated work on arithmetic. To Al-Sūfī... is also credited a large work... and similar treatises by other writers..."
