“Purpose Driven” megachurch pastor Rick Warren will be spending his Fourth of July speaking to up to 40,000 Muslims in the nation’s capital. Warren, whose network of pastors spans over 160 countries, is expected to speak during the main session of the Islamic Society of North America (ISNA)’s 46th annual convention, which has as its theme “Life, Liberty, and the Pursuit of Happiness.”

“Prominent, sought after scholars will address the theme of the convention at large,” they add. “The session is both relevant and meaningful to Islam in North America.”

Since Sayyid Syeed, a longtime leader with ISNA who focuses on building the organization's interfaith ties, invited Warren to speak during a White House gathering they attended last year, the Southern California pastor has refrained from making any public comments regarding the invitation.

But Syeed told The Indianapolis Star, the largest newspaper in Indiana, where ISNA is based, that Warren “realizes that it is equally critical for him to work with people of other faiths."

The Islamic Society, an umbrella association for tens of thousands of Muslims, has reportedly worked for years to persuade leaders of other faiths to attend its convention – a massive family reunion that draws about 30,000 people. The Islamic Society says the U.S. Agency for International Development (USAID), U.S. Department of State, U.S. Department of Homeland Security, and the U.S. Department of Justice will be among the agencies represented during a session Saturday on “Government Outreach to the Muslim American Community.”
