The struggle for the Islamic Revolution took place at a time when the so-called superpowers had divided the world into two Eastern and Western blocs.
Researchers and scholars believe that one of the most important requirements of justice from Imam Khomeini's perspective is the combat against oppression.
He launched incessant struggles against oppression, injustice and tyrants both in word and action culminating in the victory of the Islamic Revolution of Iran, thus achieving the greatest goal of his struggle.
One of the foremost measures taken by the Imam both in theoretical and practical realm aimed at realizing justice and struggling against oppression and tyranny was writing the book entitled 'Kashf al-Asrar' in 1963. In this book, he rejected the claims made by the author of the book entitled ‘One Thousand Year Secrets’, who was in favor of the measures taken by the regime ruling Iran. In the concluding section of the book we read:
"To conclude, authors of books or newspapers are requested to enlighten the nation with their literary courage and self-sacrifice hand in hand, reviving the sense of religiosity suppressed in the long past years so as not to be taken advantage by others."
In those days, in a letter addressed to the entire strata of the society called the people to rise up in the cause of God and combat oppression and injustice.
"If you lose the opportunity and fail to rise up for God and refuse to uphold religious rituals, a handful of profligate lust-seekers will dominate you and will make all your rituals and honor a plaything of their corrupt intentions."
