The movement of Salafism constitutes part of the Islamic history of fundamentalism. They call their self as Salafis, who etymologically means “what had passed through and gone before” or “the outdistancing group”. The appearance of Global-Salafism apparently starts from the will of coming back to the past, which is the period of as-Salaf ash-S{âlih}. In the next development, it had to deal with the shifting perspective from theological nuance into political movement (Jihad-Salafism) which well issued by the appearance of phenomenon of many radical movements. Discourse about Salafism therefore is actually being pretentious after the tragedy of World Trade Center (WTC), September 11, 2001. Salafism is Islamic radical movement which attempts to modify Islamic traditional legacy. Unlike other group on Islamic movement that use religious reform within their progress, Salafism uses retrograde process as practical method.
