The book begins with a discussion of the sacred nature of Makkah Al-Mukarramah, the boundaries of the Haram (Sanctuary) and its sanctity. Then it discusses the superiority of Makkah and narrates Ahadith to that effect. Then it mentions the names of Makkah and the significance of these names. This book also speaks of Ibrahim (Abraham) and Isma'il (Ishmael) (peace be upon them) and their connection to Makkah and its sanctity and development.
This book gives a clear explanation of the Muslim sound Creed which is the core of the religion of Islam, as the belief in Tawhid (monotheism) is the purpose for which Allah created both mankind and jinn, and thus, those whoes belief in Tawhid is corrupt, are not considered Muslims.
