jihad
Masaedat ibn Sadaqih said that Imam Sadiq (a.s) was questioned about the Prophet’s statement: “The best form of Jihad is expressing what is just in the presence of an oppressive ruler.” Imam Sadiq (a.s) said: “This act will only be accepted of him if his enjoining the right is based on knowledge, otherwise it is not accepted.” (as narrated in Mishkat al-Anwar, ch. 13, #241)
