Religious preaching (da'wa) has been the primary mode of action of the Islamic movement in Israel since its very beginning in the early 1970s. As part of the larger Islamic movement inspired by Hasan al-Banna and the Muslim Brothers society, however, the Israeli Islamist activists understood da'wa as an inclusive practical project of social welfare, community building, and political involvement rather than as mere speech act. Curving themselves a space between the nationalist and communist movements, they called upon the Palestinian Arabs to return to Islam as the key to personal and collective salvation. Ideas of jihad entertained among some youth in the movement, especially in the wake of the Islamic revolution in Iran (usrat al-jihad), were quickly suppressed by the Israeli security forces. Still, like in other countries the Islamic movement in Israel is divided between two wings. One, the so called northern faction, is more radical and under the leadership of Ra'id Salah espouses a confrontational attitude toward the Jewish state. The other – the southern faction – follows the moderate course suggested by Abdallah Nimr Darwish and seeks accommodation. The split occurred in 1996 over the explicitly political question of participation in the national elections to the Knesset. While the radicals boycotted them to avoid recognition of the Jewish state, the moderates saw them as a golden opportunity to advance civil rights and equality for Israel's Arab citizens. The aim of my proposed presentation is to analyze the interface between religious preaching and politics among the two factions of the Islamic movement in Israel. I argue that their religio-political position are reflected as well as shaped by their divergent ideological and practical conceptualizations of da'wa. My sources include published materials of and on the two factions – books, magazines, newspaper reports etc. – along with interviews with their principal leaders and ideologues, and observations of their activities in the Knesset, in civil society, and among the Arab community in Israel at large.
