Zaky Mallah may have had the final word during a stoush with a federal MP on ABC's Q&A, but Waleed Aly didn't give him an inch during a combative interview on Channel Ten's The Project on Tuesday night.

Aly accepted no side-stepping from Mallah, 31, who made national headlines after he said Australian Muslims were justified to travel to Syria to join Islamic State during his appearance as a vetted questioner in the Q&A audience on Monday night.

The reports over-egged Mallah's parting comment, directed at Foreign Affairs and Trade Parliamentary Secretary Steve Ciobo, which was: "The Liberals have just justified to many Australian Muslims in the community tonight to leave and go to Syria and join ISIL because of ministers like him."
