are considered usurpers, notwithstanding their having been "elected" through some sort of conciliar deliberation (which the Shia do not accept as a representative of the Muslim society of that time). The largest Shia grouping—the Twelvers branch—recognizes a series of Twelve Imams, the last of which (Muhammad al-Mahdi, the Hidden Imam) is still alive and the Shia are waiting for his "reappearance". Theoretical perspectives on democracy Al-Farabi The early Islamic philosopher, Al-Farabi (c. 872–950), in one of his most notable works Al-Madina al-Fadila, theorized an ideal Islamic state which he compared to Plato's The Republic. Al-Farabi departed from the Platonic view in that he regarded the ideal state to be ruled by the prophet, instead of the philosopher king envisaged by Plato. Al-Farabi argued that the ideal state was the city-state of Medina when it was governed by Muhammad, as its head of state, as he was in direct communion with God whose law was revealed to him. In the absence of the prophet, Al-Farabi considered democracy as the closest to the ideal state, regarding the republican order of the Rashidun Caliphate as an example within early Muslim history. However, he also maintained that it was from democracy that imperfect states emerged, noting how the republican order of the early Islamic Caliphate of the Rashidun caliphs was later replaced by a form of government resembling a monarchy under the Umayyad and Abbasid dynasties. Varieties of modern Islamic theories Muslih and Browers identify three major perspectives on democracy among prominent Muslims thinkers who have sought to develop modern, distinctly Islamic theories of socio-political organization conforming to Islamic values and law: The rejectionist Islamic view, elaborated by Sayyid Qutb and Abul A'la Maududi, condemns imitation of foreign ideas, drawing a distinction between Western democracy and the Islamic doctrine of shura (consultation between ruler and ruled). This perspective, which stresses comprehensive implementation of sharia, was widespread in the 1970s and 1980s among various movements seeking to establish an Islamic state, but its popularity has diminished in recent years. The moderate Islamic view stresses the concepts of maslaha (public interest), ʿadl (justice), and shura. Islamic leaders are considered to uphold justice if they promote public interest, as defined through shura. In this view, shura provides the basis for representative government institutions that are similar to Western democracy, but reflect Islamic rather than Western liberal values. Hasan al-Turabi, Rashid al-Ghannushi, and Yusuf al-Qaradawi have advocated different
