The Muslim Imam who led a segregated prayer session outside Britain’s Houses of Parliament on Friday lunchtime has published blogs defending terrorist Osama Bin Laden, a terrorist convict nicknamed “Lady Al Qaeda”, and previously launched scathing attacks on homosexuals and Jewish people, Breitbart London can exclusively reveal.

Abdullah Hasan, who fronts the Muslim Climate Action group, as well as the Imams Against Domestic Abuse website, led the Parliament Square prayer on Friday, which Breitbart London estimated was attended by around 200 worshippers. Mr Hasan claims there were more like 400-500 “brothers and sisters” in attendance.

Alhamdulillah, a very good afternoon. Around 400-500 brothers and sisters attended the Khutbah on climate change… http://t.co/x16iAWdOyp — Abdullah Hasan (@Abdullahhasan) October 9, 2015

But his attendance and hour-long speech followed by prayers outside the Houses of Parliament will cause concern, given his history of defending anti-Western terrorists, as well as his rabid hatred for homosexuals and Jewish people.

Mr Hasan is also alleged, according to anti-extremism pressure group Stand for Peace, to have spoken out in favour of radical hate preacher Haitham al-Haddad, though his own Facebook posts on the matter have been deleted.

He wrote on Facebook in 2013: “The Jews are still waiting for their Masih (Messiah) and they will be amongst the followers of the dajjal (devil). In the city of Isfahan (in central Iran) their [sic] will be 70,000 Jews who will be his followers.”

He said in 2012: “‘Gay marriages will lead to the destruction of Humanity’. (Pope). One issue I agree with the Pope” and has posted links on his website to claims that child abuse causes homosexuality.

Though not originally advertised as such, the event took place in conjunction with the Islamic Relief, an organisation proscribed by the government of the United Arab Emirates. The State of Israel also added Islamic Relief to its banned list, alleging that the group was assisting terrorist group Hamas. Britain’s Charity Commission cleared the organisation of any such links during an investigation, but critics still maintain concerns which are posted online.

Perhaps most disturbingly, Mr Hasan has previously posted on his blog about the death of Osama bin Laden, with the author, Yamin Zakaria, noting:

Unlike Saddam Hussein and his ilk, Usamah Bin Laden died fighting like a Mujahid, as the old proverb says, he who lives by the sword, dies by the sword. … It is simplistic to call Usamah Bin Laden a terrorist, when his opponent has murdered much more civilians in Iraq, Palestine and Afghanistan, that pre-dates 9/11. Likewise, to call Usamah a religious fanatic is hypocritical, when George Bush is the one claimed to be talking to God who allegedly inspired him to launch the war on the innocent people of Iraq. It is ironic that the Christian God of ‘love’ would order one to wage to war, rather than to turn the other cheek! … Usamah also had far more integrity than Tony Blair, unlike Blair he never lied and was generous with his wealth, constantly helping the needy…

Mr Hasan added his own commentary to this in 2014, almost three years after the original blog was published, claiming: “Extremists like Usama Bin Laden and those who claim to fight evil thrive on painting this evil and dull world for disenfranchised youth who assume he is speaking sense while knowing that they are vulnerable and weak. It is not based on religion or any authentic Islamic principle.”

His update came just hours after he was attacked by the Stand for Peace website for publishing the hagiography of Bin Laden. He has also blogged at length about his insistence that Muslims in the West should not celebrate Christmas.

The Harry’s Place website has noted that Mr Hasan has worked at the notorious East London mosque, which was set to host a live stream event featuring Al Qaeda recruiter Anwar Al-Awlaki in 2008, advertised using a picture of New York City coming under a hail of fire from meteors.

Al-Awlaki is believed to have been complicit in the radicalisation of Umar Farouk Abdulmuttalab, the London student who snuck a bomb into his underwear during a trans-Atlantic flight. The preacher, a U.S. citizen at the time, was killed by a CIA predator drone in Yemen in 2011.

And according to Harry’s Place, Mr Hasan said of “Lady Al Qaeda”, convicted terror suspect Aafia Siddique: “The situation with our sister Aafia Siddiqui and our other brothers and sisters is not ambiguous. It’s very clear. She’s not a terrorist. She’s not a terrorist wanting to blow up buildings and so on and so forth. How can she be a terrorist if she had children, and she was going out with her bag and so on and so forth. She’s not a terrorist, she was a Muslim trying to practise Islam.”

Her release date from prison in Fort Worth, Texas, is 2083.

He is also alleged by the blog to have said, though YouTube videos have since been deleted: “There are many other brothers and sisters in Bagram, in Guantanamo Bay, who are being harmed, day in, day out. Why? Their blame was nothing but they believe in Allah. This is why they are being tortured day in, day out. And we have to respond to the call of Allah [to support them].”

Harry’s Place adds:

Hasan’s fellow speakers at the meeting were two of the Tipton Three, who went to Afghanistan in 2001 for “charity work” and just somehow ended up in a terrorist training camp; Cageprisoners’ trained parrot Andy Worthington; Uthman Lateef, another supporter of terrorist suspects who tells Muslims they should not help the police; Hamza Tzortzis, who has said Muslims “reject the idea of freedom of speech, and even the idea of freedom”; and Ilyas Townsend of the Lewisham Islamic Centre, one of London’s worst extremist hotspots.

The Muslim Climate Action group appears to be a subsidiary of MADE in Europe – the Muslim Action for Development and Environment group – which runs a campaign called #BuyPalestinian, claiming “Fair Trade is Islamic Trade” which it claims it works in partnership with Oxfam on.

Oxfam has also been implicated in connections with Islamists.
