[3] During Abu Usamah's tenure at Green Lane Masjid, he was among a group of preachers whom were the focus of the Undercover Mosque program which was first aired on 15 January 2007 by Channel 4.
[4] In addition to this, on 10 August 2017 the West Midlands Police also raised a formal complaint to Ofcom regarding what it considered to be a "completely distorted" view of the intended message by Abu Usamah and the other preachers.
[7] According to a report by the Centre for Social Cohesion, Usamah "advocates holy war in an Islamic state; preaches hatred against non-Muslims; that apostasy and homosexuality are punishable by death; and that women are inferior to men", following an undercover recording of him preaching to his congregation which featured in a Channel 4 Dispatches episode on radical Islam at British universities.
"[3] Usamah was invited to speak at events held by University College London's Islamic Society on 1 February 2008 and 6 September 2009.
[8] He was invited to speak at the same venue on 30 November 2009, but the event was cancelled due to pressure from gay rights and anti-extremism campaign groups.
