During the reign of Shah, a blasphemous book was written against religious circles and values. The book had wrongly targeted the divine values of the society and had raised several questions about the religious and Islamic historical personalities.
Seeing that, Imam decided to suspend all of his activities and got engaged in answering the suspicious raised by the blasphemous author.
Imam’s book known as Kashf al-Israr, which has deep religious concepts, was written within period of forty days. Imam through this work had given reasonable and academic answers and the book remain a great source of inspiration for believers and faithful people.
