Izzadeen, along with well-known Islamic extremist Anjem Choudary, appeared together in a youtube video published in 2015 urging Muslims not to vote in parliamentary elections as it is prohibited in Islam as shirk, an unforgivable crime. He also stated that Muslim members of Parliament were apostates. Izzadeen fervently advocated against Kufr (non-Muslim) law in the United Kingdom and cited lack of British intervention in Syria and the "Occupation of Palestine" as support for the "murder of children."Isil supporters cheer Westminster attack as 'revenge' for British air strikes on Syria https://t.co/2wC79pTRH7 pic.twitter.com/e7a7UJnrNw
