Born to a modest family in Al-basra 168 H/ 78 A.D., spent most of his life in Baghdad, with a distinguished record of achievements, Mohammad Ibn Sa'd has built a reputation as one of the major scholars in history, Hadith, Islamic Fiqh, language and lineology. Ibn Sa'd is known most for laying the foundations for authorship, text analysis and criticism. His most renowned work Kitab Al-Tabaqat Al-kubra was classified as an encyclopedic chronicle of Islamic history, science, politics, economics and sociology up to the year 230 H/ 844 A.D. The book was also considered a classic in the synchronic depiction of social class. This study critically examines Ibn Sa'd's aims from writing history in an attempt to provide new insights into the historical method the author used in his classic work.
