While Muslim men kneel in prayer, a group of Christians, Mormons and even non-religious people looked on. The mosque is attended by more than 3,000 people, but its attendees say they want to get more involved with the community.
Tahir Amin Kayum says it's important for Muslims to interact with people of other faiths.
"Right now a lot of people are not familiar with Islam," he says. "Or they don't know Muslims, and if they know Muslims they don't know that they know they're Muslim. So what they see and what they hear about Muslims is what they hear on television, which, we know a lot of times, can be misconceptions."
Local officials, including Virginia Congressman Jim Moran, also attended the outreach event.
