BEIJING — The Chinese government, further tightening its grip on Muslims in western China, has prohibited parents from choosing names like “Muhammad,” “Arafat” and “Jihad” for their children.

Officials described the ban, introduced this month, as part of an effort to “curb religious fervor” in the western region of Xinjiang, home to more than 10 million Uighurs, a mostly Muslim minority group.

The government considers Xinjiang a hotbed of Islamic extremism, violence and separatist thought. But many Uighurs say the government’s strict limits on worship and speech are responsible for tensions in the region.

The list of names, a copy of which was provided to The New York Times by Uighur activists, is titled, “List of Banned Ethnic Minority Names.” It bans more than two dozen names, including “Mujahid” and “Medina.”
