Imamah", "The Clergy", "Government", "Law", and "
Hadith". In the first chapter, "Tawhid", Khomeini answers criticisms of Shia Islam by
Baháʼí Faith. The second chapter contains
Hadith of Position,
Hadith of the two weighty things, and proof of the concept of Imamah by verses of the
Quran. The book's third, fourth, and fifth chapters include a discussion of government in the contemporary age. At the end of
The Thousand-Year Secret, Hakamizada asks some challenging questions and invites responses from readers. At the beginning of the third chapter of
Kashf al-Asrar, Khomeini responds to five of the nine questions asked in
The Thousand-Year Secrets. == Reception ==
