"There is an entire network of mosques like that across America..."
The former Department of Homeland Security agent spoke of Muslim Brotherhood affiliated agents and mosques. Below is the Koran verse (8:60) referred to in the Muslim Brotherhood logo and slogan:
Sahih International: And prepare against them whatever you are able of power and of steeds of war by which you may terrify the enemy of Allah and your enemy and others besides them whom you do not know [but] whom Allah knows. And whatever you spend in the cause of Allah will be fully repaid to you, and you will not be wronged.
