Apostates Non-religious Lukewarm
Malaysia has three Major races: Malays, Chinese, and Indians
By the Malaysian Constitution, all Malays are Muslims by law. Of course there are apostates (who believe in other religions secretly), non-religious (atheists and agnostic etc), and lukewarm (who still identify themselves as Muslims but not following many of the rituals) Malays. But religious Malays are predominant, accounting for perhaps 60-90% of Malays.
