The Islamic Society of North America will hold its convention in Washington, D.C., over the Fourth of July weekend. The society is hoping that President Obama will appear.

Even if the President doesn’t make it, attendees will hear Rick Warren of Saddleback Church participate in a panel discussion along with noted Islamic scholar Hamza Yusuf.

The Islamic Society expects the conference to attract 40,000 Muslims from across the country.

“It is critical for us to have positive relationships with people of other faiths,” said Sayyid Syeed of the Islamic Society. Syeed’s focus in the organization is building interfaith ties in America.
