Zohran Mamdani will be first mayor to be sworn in on Quran during New York City inauguration

Mamdani, a 34-year-old Ugandan-born socialist, will be the first Muslim mayor of New York City and the first mayor to be sworn in using the Quran, the central religious text of Islam.

He will use two family Qurans, as well as one that belonged to writer and Puerto Rican activist Arturo Schomburg, who built the foundation for Harlem's Schomburg Center for research in Black culture.

Mamdani has openly voiced his belief that Israel's military campaign in Gaza is "genocide," denying Israel is a Jewish state and failing to condemn the violent slogan "globalize the intifada."

During a news conference announcing Kassem's appointment, Mamdani said, "I will turn to Ramzi for his remarkable experience and his commitment to defending those too often abandoned by our legal system."
