Chapter 2 is devoted to sources attributed to pre-ᶜAbbāsid writers, who lived and wrote during the Umayyad Caliphate: Sulaym ibn Qays (d. 76/695), Ibn Shihāb al-Zuhrī (d. 124/741), and Mūsā ibn ᶜUqba (d. 135/752). These sources are problematic for various reasons, examined extensively in the first section of the chapter. The chapter then focuses on the literary descriptions of conversion and detectable themes. This chapter demonstrates how the earliest available historical reports include precursors of conversion themes, which are to be developed, used, or reinterpreted under the ᶜAbbāsid rule. Chapter 2 argues that, since the genesis of Muslim historical writing, religious historians not only emphasized conversion but also used it to advance their religious views and support their political agendas.
