"Hizb ut-Tahrir is a political party whose ideology is Islam, so politics is its work and Islam is its ideology. It works within the Ummah and together with her, so that she adopts Islam as her cause and is led to restore the Khilafah and the ruling by what Allah (swt) revealed. Hizb ut-Tahrir is a political group and not a priestly one. Nor is it an academic, educational or a charity group. The Islamic thought is the soul of its body, its core and the secret of its life.
Hizb ut-Tahrir was established in response to the saying of Allah (swt),
“Let there be among you a group that invites to the good, orders what is right and forbids what is evil, and they are those who are successful” [TMQ 3:104]
Its purpose was to revive the Islamic Ummah from the severe decline that it had reached, and to liberate it from the thoughts, systems and laws of Kufr, as well as the domination and influence of the Kufr states. It also aims to restore the Islamic Khilafah State so that the ruling by what Allah (swt) revealed returns.
Its aim is to resume the Islamic way of life and to convey the Islamic da’wah to the world. This objective means bringing the Muslims back to living an Islamic way of life in Dar al-Islam and in an Islamic society such that all of life’s affairs in society are administered according to the Shari’ah rules, and the viewpoint in it is the halal and the haram under the shade of the Islamic State, which is the Khilafah State.
