Many of the ideological concepts and doctrines of Hizb ut-Tahrir (Party of Liberation) and the Islamic State (IS) are similar. They both believe in the goal of establishing Islamic caliphate rule and in the strict interpretation of Islamic law. The two groups differ, however, in one major respect: Hizb ut-Tahrir stands categorically against the use of violence and military means to realize its ideals.
“We are against any use of material means to accomplish our goals,” Musab Abu Arqoub, a Palestinian Hizb ut-Tahrir leader, told Al-Monitor by phone from the town of Dura, in the Hebron district.
