Usama Hasan is a British Senior Analyst at the Tony Blair Institute for Global Change and has described himself as a "a full-time counter-extremism practitioner since 2012".

[13][14] Hasan was a member of the United Kingdom's Foreign and Commonwealth Office's Projecting British Muslims delegations to Egypt in 2008[15] and to Afghanistan (Helmand) in 2010,[16] was a Keynote Speaker at the Anglo-Syrian government-sponsored conference "The Message of Peace in Islam" in Damascus in 2009,[17] and is a Patron of both the Forum for the Discussion of Israel and Palestine (FODIP)[18] and Friends of the Bereaved Families Forum.

[31] According to the website of the Masjid al-Tawhid, the Hasan family "want to ... regain personal control of the mosque" and the vice chair Mehmud Patel said that "the mosque has 'effectively been run as a family affair, not a charity' by Usama Hasan and his father Suhaib Usama, and conflict as a result of the trustees' attempts to move away from this model of operation was inevitable".

[32][33] In October 2013 Hasan was alerted by anti-terrorist police that he and other Muslim figures in the UK who had spoken out against Islamist extremism had been targeted by a propaganda video created by Al-Shabaab, the terrorist group responsible for the attack on the Westgate shopping mall in Kenya.

Their fatwa "religiously prohibites" would-be British jihadists from joining the Islamic State and orders all Muslims to oppose ISIL's "poisonous ideology".
