Al-Muhajiroun

Al-Muhajiroun (literally "The Emigrants") was a British-based Islamist organisation, membership in which has been

History
The group was founded on March 3, 1983 by Omar Bakri Mohammed following his exclusion from the Islamist party Hizb ut-Tahrir. Despite becoming active predominantly in Britain, al-Muhajiroun was actually established in Mecca and launched in Jeddah. Mohammed was later expelled from Saudi Arabia after protesting its government (on the grounds that the regime was "man-made") and came to Britain in 1986.

The spread of their asshattery

 * Al-Ghurabaa, believed to be an offshoot of al-Muhajiroun, was banned in 2006 under new legislation outlawing the glorification of terrorism.


 * The Saved Sect, another believed al-Muhajiroun offshoot, was banned at the same time as al-Ghurabaa. Parts of its website can still be read on Archive.org, including an, erm, enlightening hypothetical conversation between a secularist and a Muwahhid.


 * Two more of the groups that the government decided were al-Muhajiroun under different names. Beyond that... eh, who cares?


 * Islam4UK was a web-based organisation describing itself as "a platform" for al-Muhajiroun, founded by Bakri Mohammed and at one point led by Anjem Choudary.

Their bullshit is banned by the UK Government
As mentioned above, the British government banned Al-Ghurabaa and the Saved Sect in 2006. In 2010 it decided that al-Muhajiroun, Islam4UK, Call to Submission, Islamic Path and London School of Sharia should be treated as the same organisation that had operated under those two names and similarly banned.

Following the ban another group, Muslims Against Crusades, sprang up only to be similarly banned.

Their connections to terrorism
Four men who planned to detonate a bomb at the London Stock Exchange in 2010 were reportedly connected to Al-Muhajiroun; one, Mohammed Chowdhury, had previously been photographed holding an Islam4UK placard. One of the killers responsible for the 2013 Woolwich attack also had a background in the group, as did London Bridge attacker Khuram Butt. Omar Sharif, who was found dead after his suicide vest failed to explode, reportedly attended its meetings. Zacarias Moussaoui, currently serving life without parole for involvement in the 9/11 attacks, also has links to Al-Muhajiroun, as does "shoe bomber" Richard Reid. One member was jailed for attending a terrorist camp.

Considering the group's leader is a convicted ISIS sympathizer, none of the above should come as a surprise.
