Abd al-Karim Qasim
During the days of the red tide, under the rule of Abd al-Karim Qasim, al-Qazwini supported Ayatollah Sayyid Muhsin al-Hakim's fatwa deeming communism an infidelity and atheist. He took a strong stance against Qasim, by rejecting to join the iftar he had prepared for the religious convoy in Ramadan, 1960, which lead to his imprisonment, making him the first cleric to become a political prisoner in Baghdad.
