Islam in America is growing exponentially. From 2000 to 2010, the number of mosques in the United States jumped 74 percent.
Today, there are more than 2,100 American mosques but they have a challenge: There aren't enough imams, or spiritual leaders, to go around.
The Mid-Cities Mosque in Colleyville, Texas, has two modest minarets that distinguish it as a sacred building here in this sedate suburb between Fort Worth and Dallas. It's trimmed in green lights — the color of Islam. A Dallas Muslim Yellow Pages sits in a rack outside the doors.
