2jay posted an article on Chinese Muslims a few months ago. Here is an excerpt.
Ms Mah is the eldest of three children of a Shanghai businessman of Hui or Uyghur descent, whose family has been embraced the Islamic faith for generations. Her family moved to Singapore in the late 1920s and she remembers growing up in a very Chinese environment.
“We celebrated Chinese New Year, the Mid-Autumn Festival, and with my non-Muslim cousins too. The only difference was that we did not eat pork.”
She estimates there are only a handful Chinese Singaporeans whose families arrived here as Muslims. And they are something of a curiosity, especially to other Chinese. “Each time a contractor or handyman comes by and sees me, he will say, ‘Oh you are Muslim? What is this religion all about?” she says with a chuckle.
She also has some information about Malays in Singapore who have converted out of Islam.
