The discussion on the Islamic State throughout the current affairs talk show was tense but became even more heated when host Jenny Brockie turned the conversation towards cancelled passports.

Nineteen-year-old Abu Bakr has had his passport cancelled by Australian authorities.

After being probed on the matter, he walked off the set.

Abu Bakr, a Muslim of Iraqi and Italian background, said he thought Muslims were obligated to help fellow Muslims overseas.

He also said he believed that the Islamic State represented the purest interpretation of the Islamic holy book, the Koran.

The Department of Foreign Affairs and Trade has classified the Islamic State as a terrorist organisation.

Other Islamic youth representatives on the program completely disagreed with Abu Bakr.

"We've got family in Iraq who have experienced all of this, you cannot say that," said guest Ninva Yakou.

"For ISIS to claim that they are just fighting for Islam is just a joke, they don't fight for anyone but themselves and their so-called state," said guest Yehya El Kholed.

Abu Bakr felt that Muslims were being unfairly targeted by Australians.

“In order for me to be connected to the values here of Australia, the Australian government needs to stop picking on the Muslims here,” Abu Bakr said during the program.

"Whenever you express your opinion of a tyrant, you are subjugated to being a terrorist or subjugated to being a national threat," he said.

Abu Bakr arrived at the program wearing the flag of the Islamic State, a group reportedly responsible for massacres and mass beheadings in Iraq.

Another Australian supporter of the Islamic State, Mohamed Zuhbi, appeared on Insight via a Skype link from Turkey.

Born in Syria, Mr Zuhbi has lived in Australia since the age of one.

He said he was currently undertaking humanitarian work but had crossed the Syrian border a number of times.

"I believe that [Islamic State] are the future of Syria," he said.

"I believe that they're the future of the Islamic empire to come."

Another Australian Islamic State supporter, Abdul Salam Mahmoud, said he was also working in a humanitarian capacity in Syria.

"In Islam we're obligated. Wherever our people are being harmed or being oppressed it's an obligation for us to go and help them to fight tyranny and to fight oppression," Mr Mahmoud said.

He explained what humanitarian work he was doing with the Islamic State.

"We give monthly payments to families who have orphans and widows and we give them food packages," he said.

Australian National Imams Council spokesman Sheikh Mohamadu Saleem was concerned by the number of young Australian Muslims fighting with the Islamic State.

"There is a very small number of people ... who are not listening," he said.

"But the large number of people who are in schools, in the universities, doing the right thing, they are listening."

Sheikh Saleem said that it was not the duty of Australian Muslims to fight overseas.
