There are many people who try to argue that Hizb ut-Tahrir is a non-violent organisation. That we can use them to prevent al-Qaeda style extremism. That they really only represent a peaceful opposition movement to current regimes around the world. This is not the case.
This is a guest post by Abdul Qadeem Zallum, global leader of Hizb ut-Tahrir between 1977 and 2003.

[T]he issue pertaining the obligation of ruling by Islam and preventing the rule by Kufr is a vital issue, because the Legislator (swt) has made the measure that should be undertaken towards it a measure of life and death; thus, he who does not rule by Islam and rules by a Kufr system should either retract or be killed.
