Hardliner tells gathering in Sydney’s west that capitalism has failed and criticises US-led campaign in Iraq and Syria

A hardline Islamic leader from a group advocating an Islamic caliphate says Muslims should be ready to make sacrifices to achieve it.

“We believe this world deserves a new world order,” Ismail Al-Wahwah declared at an event headed by the controversial Hizb ut-Tahrir organisation.

More than 200 people attended the lecture at Lakemba in Sydney’s west on Friday night where Al-Wahwah, a sheik from Bankstown, denounced Australia’s involvement in the US-led campaign in Iraq and Syria aimed at fighting Isis extremists.

The crowd was engaged and calm except for a moment of slight tension when an audience member asked the sheik about the penalty under sharia law for a Muslim leaving the Islamic faith.

A 70-year-old woman also hit out at Al-Wahwah for criticising Australian values and told him to stop waving his finger around.

Hizb ut-Tahrir advocates that secular governments be replaced and Muslim-majority countries unite under a global caliphate governed by Islamic law.

Al-Wahwah said capitalism had stopped leading the world and Muslims were ready to make sacrifices.

“If you want to change, you have to pay the price,” the preacher told the lecture – titled The War to End a Blessed Revolution.

Weeks after 16 people were detained in a counterterrorism operation across western Sydney, Al-Wahwah denounced the police officers who burst into the bedrooms of Muslim women in the pre-dawn raids.

Australian civilisation would pay the price for this for a thousand years, he said. “Who is going to fix the harm done to the women?” he asked.

The prime minister, Tony Abbott, said earlier this week that Hizb ut-Tahrir was a deplorable organisation that had an ideology that justified terrorism.

Al-Wahwah shot back and criticised Australia’s involvement in the US-led operation in Iraq.

The issue was not Iraq or Syria but America wanting to control the world, he said.

“This new invasion will kill hundreds of thousands again and the blood will be on the hands of politicians again,” he said.

Meanwhile it was reported that the convicted terrorist Abdul Nacer Benbrika has been influencing jihadist recruits from prison in a quest to become the spiritual leader of a new generation of Australian extremists.

Concerned over his growing influence, authorities have moved him to a different Victorian prison after several of his followers travelled to Syria to fight with the Islamic State group after visiting him in jail, News Corp Australia reported on Saturday.

Quoting security sources, News Corp says authorities believe Benbrika is seeking to model himself on jailed Indonesian cleric Abu Baku Bashir, the spiritual leader of the Bali bombers, who recently embraced Islamic State.

A self-proclaimed Islamic cleric, Algerian-born Benbrika is serving a 15-year jail term for leading a terrorist group in 2005 that talked of attacking Melbourne’s Crown casino and bombing the MCG.
