Has evolved in some very interesting ways where 18% of the population is Muslim.
In fact Singapore has Sharia mediation courts and a Sharia appeals court much like the ones Canada is considering. The Islamic Religious Council of Singapore or Majlis Ugama Islam Singapura deals with the government on Islamic matters. The group is responsible to look after social, religious, and welfare needs of the Muslims in Singapore. Its functions and processes are set out in the Administration of Muslim Law Act.

Heck, Singapore itself is a very interesting place where Islam, Christianity, Buddhism and Hinduism co-exist side by side.
