A thief dressed in all white broke into a Queens mosque and made off with $1,500 from a donation box Wednesday night, cops said.

The crook forced his way through the rear door of the Islamic Center of Bosnia and Herzegovina on Crescent Street near 38th Avenue in Long Island City around 9 p.m., according to police.

He then used an unknown tool to pry open the donation box and swiped the cash, before breaking through an office door and snatching more money from a desk drawer, officials said.
