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.
