Hizb ut-Tahrir is a political party whose ideology is Islam. The party works throughout the Islamic world to resume the Islamic way of life by re-establishing the Islamic Khilafah "Caliphate" (Caliphate). The party adheres to the Islamic Shari'ah in all aspects of its work, and takes its methodology from that of the Prophet Muhammad that he used to establish the first Islamic State in Madinah. The Prophet Muhammad limited his struggle for the establishment of the Islamic State to the intellectual and political domains. Hence the party considers violence or armed struggle against the regime a violation of the Islamic Shari'ah. 

The Party has been clear, open and challenging in the carrying of its thoughts and in confronting the false thoughts and political parties, both in its struggle against the colonialists and in its struggle against the corrupt Muslim rulers - this has exposed it to severe harm committed by the rulers against it; such as imprisonment, torture, deportation, pursuit, attacking members livelihoods, impairment of interests, banning from travelling and murder. The oppressive rulers in Iraq, Syria, Libya, Uzbekistan and others have killed dozens of its members. The prisons of Jordan, Syria, Iraq, Turkey, Egypt, Libya and Tunisia are full of its members. Though Hizb ut-Tahrir committed itself to be open, clear and challengingly in its call, it restricted itself to political actions alone and did not exceed them by resorting to material actions against the rulers or against those who opposed its call, following the example of the Messenger of Allah who restricted himself in Makkah solely to the call and he did not carry out any material actions until he had migrated to Madinah.
