Farrakhan said if Jesus Christ and Mohammed were onstage with him, they would embrace each other with love, but the world is at war because the religions are divided, the Detroit News reported.
"Our lips are full of praise, but our hearts are far removed from the prophets we all claim," Farrakhan told an audience at Ford Field. "That's why the world is in the shape that it's in."
The three-day convention was billed as an interfaith event with a focus on unity within the faith. Leading Muslim scholars, as well as top-ranking members of the Nation of Islam, traveled to Detroit for the event and joined 5,000 others in the Jumu'ah prayer Friday, the newspaper said.
The speech is expected to be the last public address by Farrakhan, who underwent extensive surgery earlier this year.
