The surveillance footage is brief, but it's one of few clues investigators have to go on.
Awni Kussad, an elder at the mosque, says the video shows what appears to be two young men going to the back of the building, carrying what may be a can of accelerant.
"They are bad kids and that's about it. Someone decided to do something wrong and evil is everywhere and that's the bottom line," Kussad said.
The suspects are seen in the video running to a getaway car.
"If you have a problem with the mosque and you like to build fires, we can go build a little fire somewhere. If you want to ask me or find from me what we are all about, we'd be happy to talk to you," Kussad said. "Don't just come and burn a place -- any place for that matter -- and run away like that."
The alarm sounded when glass was broken, but there was also someone staying inside the mosque who called 9-1-1.
The crime didn't stop a group of men from Sunday evening prayer. In the next room, the smell of smoke remained and you can see burn marks across the room.
"I'm sad in the least, why it happened, that's all," Kussad said.
Kussad says fortunately firefighters were able to stop it before much structural damage was done.
"It's not really a lot of damage," he said. "It's more moral damage than anything else."
