On 11 March 1946, while being tried on charges of “slander against Islam,” Kasravi and one of his assistants named Seyyed Mohammad Taghi Haddadpour, were knifed and killed in open court in capital by followers of Navvab Safavi, a Shi’a extremist cleric who had founded an organization called the Fadayan-e Islam (literally Devotees of Islam), led by two brothers, Hossein and Ali-Mohammad Emami. The same group had failed in assassinating Kasravi earlier in April 1945 in capital. Ayatollah Borujerdi and Ayatollah Sadr al-Din al-Sadr had issued fatwas for killing Ahmad Kasravi.
