A group of former Muslims have stepped into the battle over the proposed mega mosque in Murfreesboro, Tenn.

The group, Former Muslims United Against Islam, purchased a digital billboard in the city's downtown area. The billboard was designed with a green background, which the group says is the Saudi Arabian flag with the Muslim profession of faith.

The group also claims the children on the billboard advertisement represent the target of the Islamic message.

Nonie Darwish is a member of the group, and she's trying to warn the people of Murfreesboro about the hidden dangers of Islam.

"I have no problem with religious aspects of Islam, but Islam majority is a political system. We trying to alert the public," she explained.

The city's residents are divided over the proposed Islamic center.

"What would it be like if somebody said, 'Stop practicing Christianity or stop the new church from going up?'" one resident said. "That's just not right. I know you can't judge a book by its cover, but if they do practice any type of terrorism or you know there's any of that relationship then absolutely we'd have an issue with that."

Rutherford County officials have already approved the proposed expansion, but opponents are hoping they will reverse their decision.
