The wife of a terrorist recruiter has been convicted of disrespectful behaviour after refusing to stand for a judge in a Sydney court.

Moutia Elzahed, the wife of jailed Islamic State extremist Hamdi Alqudsi, was the first person in NSW to face the charge after she refused to rise for a judge in 2016 purportedly on religious grounds.

The 50-year-old Muslim woman was found guilty in the Downing Centre Local Court of nine counts of disrespectful behaviour in court.

Elzahed again did not stand but folded her arms when magistrate Carolyn Huntsman left the bench after delivering her ruling on Friday.
