WASHINGTON (CNN) - About 50,000 Muslims are expected to attend a day of prayer Friday on Capitol Hill, organizers said.
"Islam on Capitol Hill" is intended to "express and illustrate the wonderful diversity of Islam," organizers said on their Web site.
We intend to manifest Islam's majestic spiritual principals as revealed by Allah to our beloved prophet," it said.
"Likewise, we intend to inspire a new generation of Muslims to work for the greater good of all people. We shall serve all people, regardless of race, religion or national origin."
The Washington Post reported that Hassen Abdellah, the president of the Dar-ul-Islam mosque in Elizabeth, New Jersey, is the the lead organizer of the event.
Abdellah and the mosque did not immediately return phone calls for comment.
The event has drawn criticism from some Christian leaders.
"It is important for Christians to understand that Friday's Muslim prayer initiative is part of a well-defined strategy to Islamize American society and replace the Bible with the Koran, the cross with the Islamic crescent and the church bells with the Athan [the Muslim call to prayer]," said Rev. Canon Julian Dobbs, leader of the Convocation of Anglicans in North America's Church and Islam Project, in a written statement.
"The time has come for the American public to call Islam to account," he said.
