In November 2010 she was put on trial for anti-Islamic comments made during a seminar to the Freedom Education Institute in 2009: she referred to the Qu'ran as "evil" and to Islam as "hostile", and stated that "Mohammed had a thing for little girls" (referring to his marriage to 9-year-old Aisha). Reportedly, Sabaditsch-Wolff's comments were secretly recorded by a journalist from the weekly magazine NEWS who was planted in the audience.
Although acquitted of incitement, she was given a fine of 450 Euros for "denigration of religious beliefs of a legally recognized religion" (The Austrian blasphemy law[wp]) according to Section 188 of the Austrian Criminal Code.
The main objection appears to have been to Sabaditsch-Wolff's comment about Mohammed's "thing for little girls". The judge declared that Mohammed remained married to Aisha until his death, by which time she had turned 18, he must have liked adult women as well. Seems rather like splitting hairs, but there we go.
