Wearing a short-sleeved blouse and knee-length black pants with flip-flops, Betty Khoo stood out like a sore thumb among the large crowd of white-robed Muslims gathering in a community mosque located at the fringes of Kuala Lumpur.

Khoo, a Christian, waited along with the scores of white-robed Muslims for the echo of prayers signaling the time to break the fast, before tucking into a delicious spread provided by the Ah-Muhsinin mosque in this quiet residential area.

"I did wonder if I would be allowed to enter the mosque, since my legs and arms are not covered," said Khoo.
