The paper describes how the Hamas terrorist organization came to power through democratic means and how it uses the dawa social protection system to promote and support its own activities. It also explains the roots of Hamas' dawa and the function of the social service institutions as ideal tools used by Islamists to radicalize and recruit young Muslims. Of course, at first sight, there exists nothing violent nor antisocial in dawa activities. However, this is not so. A dawa organization, often created as a local volunteer society, a non-government organization, or a private volunteer organization, plays an important common role in the history and culture of Islam. Hamas has its primary goal, and it is to change the essential Palestinian national political struggle into a fundamental religious conflict. The advancement of this goal means complete transformation of Palestinian society, as compared to other relatively secular Muslim societies in the Arab world, into an ever more ardent and religiously and politically determined society.
