In a wide-ranging interview this week, Senator Hanson condemned the building of mosques, women covering their faces and the general conduct of Muslim Australians.
Aside from her criticism of Muslims' efforts to integrate, among other matters, Senator Hanson drew attention to a rarely practised Islamic interpretation known as Taqiyya.
"If you understand Islam, it's like ... they can actually lie to you. It's called Taqiyya, and they can actually tell you whatever they want to. It's to blend into a society until the numbers grow, and then they will actually then impose their will on the people or get hold of governments."
Deakin University's Mateo Vergani, who specialises in ethnicity and politics, says only fringe elements of Islam observe the version of Taqiyya she is referring to.
Dr Vergani says those elements include groups like the self-proclaimed Islamic State, or ISIS.
"Groups like ISIS, for example, use these words to suggest to certain members of the organisation to hide in a host society before the attack. So this exists, but we have to remember that those interpretations of Islam are really embraced by a tiny minority of Muslims."
Dr Vergani recently completed a study of Australians' views of Islam, based on responses to a series of factual questions around the religion.
He says the researchers compiled an index of knowledge and found people who had more prejudice against Muslims knew the least about Islam.
The recently elected Islamic Council of Victoria vice president Adel Salman says he, like many in Australia's Islamic communities, fears Senator Hanson's re-emergence.
"What concerns us the most in the Muslim community is that her views are becoming more mainstream. They're being 'mainstreamed.' And it's a case of saying, 'Who now speaks on behalf of the centre?' Are Pauline Hanson's views representative of where the debate is at?"
On his visit to the world's most populous Islamic country, Indonesia, this week, Prime Minister Malcolm Turnbull has strongly condemned Senator Hanson's views.
"Trying to demonise all Muslims is only confirming the lying, dangerous message of the terrorists."
Meanwhile, debate continues around changing section 18C of the Racial Discrimination Act, which bars acts likely to offend, insult, humiliate or intimidate others because of race or origin.
International Development Minister Concetta Fierravanti-Wells has proposed what she calls a "reasonable person" test.
She says alleged vilification should be tested against the feelings of what she calls "ordinary Australians."
"Today, the ordinary Australian, or the reasonable person in the Australian community, has had a degree of cultural, social and religious diversity as part of their lives. I think it's a workable compromise between freedom of speech and freedom from racial vilification."
Cabinet will consider the proposal in the coming weeks.
