What does the Melaka fatwa prohibit regarding beliefs that contradict Ahli Sunnah Wal Jamaah of the Asyairah and Maturidiyah schools?

Summary

This Melaka State fatwa prohibits Muslims, whether as individuals or through organisations or associations, from questioning the practices and creed of Ahli Sunnah Wal Jamaah of the Asyairah and Maturidiyah schools, and from spreading practices or beliefs that contradict it. Being a member or follower of a contradicting teaching, including while concealing it behind economic, social or political activities, is deemed to be practising a belief opposed to this creed. New variations or branches of teachings resembling such contradicting elements are declared deviant, and spreading, possessing, publishing, listening to or printing related materials is also prohibited. Violating these prohibitions is an offence that may be acted upon under the laws in force in Melaka.
