The afternoon prayer summit drew about 60 people, including a dozen Muslim, Christian and Baha'i community leaders.
Participants were urged to pray on issues that plague and divide the community, including high foreclosure and unemployment rates, substance abuse and underperforming schools.
"There are too many people out in our community who are suffering and they need to see the faith community -- all of us together -- bring about change and bring about healing," said the Rev. Roderick Pearson, president of the Islip NAACP, which sponsored the event.
"We've got to bring back some prosperity to the communities," he said. "And we believe that since no one has given us the right answer, the right answer will come from God."
Members of the audience nodded and shouted in agreement as religious leaders took turns addressing them -- some in Spanish, some in a traditional Gospel style.
"We must understand that there is no conflict between Islam and Christianity, or Islam and Judaism, or Islam and any other religion," Rehman said.
"The only conflict is between those who believe in coexistence and those who destroy human life," he said.
