The book is considered to be Imam Khomeini's first public political statement.
The great Imam is said to have written Kashf –al- Asrar in response to a pamphlet written by Ali Akbar Hakamizada in 1943.
Hakamizada’s pamphlet called as Thousand -Year Secrets (Asrar i Hizar Sala ) aimed at spreading anti-Islam propaganda. Hakamizada and some of his comrades were being employed and supported by the then monarchy Pahlavi regime.
The book is essentially a detailed, systematic critique of an anti-religious tract, and in defending Islam and spirituality, Imam refutes the deviatory sophisms employed by the author.
It is in this book that the idea of an Islamic government, and the need for an uprising to establish this, is propounded.
The victory of Islamic Revolution in 1979 under wise leadership of Imam Khomeini in Iran strengthened the oppressed nations worldwide and revived the divine teachings.
