Ibn Katheer's As-Seerah An-Nabawiyyah  is a full examination, in chronological order, of the background, life and mission of the Prophet Muhammad, peace be upon him. Drawn from the earliest and most reliable Arabic sources, it offers, in this English translation, the fullest available account of the historical circumstances and personalities most important in the founding of Islam. Ibn Katheer’s work offers a fine example of Islamic scholarship; the quotations and anecdotes that constitute its core are evaluated in terms of the trustworthiness of their sources. Variant wordings that are related through differing lines of transmission are noted, and Ibn Katheer gives both his own assessments and those of the earliest Islamic authorities concerning the likely authenticity of these records. The comments and conversations, derived from ancient texts, that are quoted in this work constitute the basis of our knowledge of Islam during the lifetime of its founder.  This is the fourth of four volumes.
