A Muslim imam says he's been forced into hiding after voicing support for the ideas of anti-Islam campaigner Ayaan Hirsi Ali.

Mohammed Tawhidi, of the Islamic Association of South Australia, said he agrees with Ms Ali's call to close Islamic schools in Australia.

He has also rejected extremist groups.

Ms Ali cancelled her tour of Australia this week because of fears for her safety.

"These schools do exist that are a problem and they need to be either shut down or changed completely," Imam Tawhidi said.

Fearing reprisals, the Adelaide-based Imam said he was escorted into hiding by police.

A video released on Facebook has been credited, in part, with stopping Ms Ali's speaking tour.

In a video, which was posted to Facebook a group of Muslim women speak out against Ms Ali saying: "You're not here to help us or stand with... you're here to profit from an industry that exists to dehumanise us".

Hana Asafiri, of the Persons of Interest group, which is behind the video, said they opposed Ms Ali because her rhetoric could inspire random attacks against Australian Muslims.

"There's nothing to be celebrated through a divisive and very hostile and fear-mongering conversation," Ms Asafiri said.

Ms Asafiri said Ms Ali cancelling her trip was seen by her group as a victory for free speech.
