Resistance Front's key players are the nations that are either a Shia nation or a nation with Shia heritage. In other words, Resistance Front owes its revolutionary spirit to the Shia creeds lived with the great founders of the front most prominenly by the Grand Ayatollah Khomeini. Shia Imams devoted themselves to the defense of the oppressed as they themselves were one of the many oppressed people in the world. In his thought provoking Last Will, Imam Khomein invites Muslim nations to pay a careful attention to the words and deeds of Shia Imams as the source of wisdom. "Never heed the temptations of the misguided enemies and beware that one deviate step would mean the prelude to the corruption of religion, Islamic ordinances and the Divinely Just and Righteous Rule. For example, never neglect the Friday congregational prayers which reflect the political dimension of prayers: This Friday prayer is among the greatest blessing that the Almighty has granted to this nation. Also never neglect the mourning ceremonies on the occasions of the martyrdom anniversaries of the Imams, particularly the master of all martyrs his Holiness Abi-Abdullah Hussein (A.S.) (much may God, His angels, the Prophets and saints bless his great and daring soul). People should be reminded that the decrees of the Imams (A.S.) for commemorating this great epic4 and whatever curses have been sent to the enemies of the Household of the Prophet are, in fact, the heroic cries of nations against the tyrannical rulers throughout history to the end. You should know that the curses against the injustices of the Umayyads, who have been eliminated from the face of earth and dropped into hell, reflect the cry of [the people] against the oppressors of the world."
