Six months after Prime Minister Najib Razak stood before the United Nations and urged Muslims worldwide to be moderate in their religion, members of his own party are supporting a law that punishes adulterers with death and thieves with amputation.

Lawmakers from Najib’s Umno joined the opposition PAS to pass Islamic criminal law, or hudud, in the opposition-held state of Kelantan. The move has drawn criticism from other parties in their respective coalitions, while human rights groups say it’s an unconstitutional step for secular Malaysia.
