I'm in Yunnan and have noticed lots of Chinese muslims and ate at one of their restaurants today. I was aware of Turkic-speaking muslim ethnic minorities in the far west of China but now I know those people, the Uyghurs, are distinct from the Hui people I have been noticing. According to Wikipedia the Hui people speak their local Chinese dialect rather than an ethnic language.
But I'm wondering if they still have some common phrases or greetings used only by Hui and not by most Han Chinese, possibly due to Islamic or Arabic language influence.
For instance do they have Sinicized equivalents to "inshallah" or the greeting "As-salamu alaykum"? Possibly translated literally or calqued into Chinese? Or possibly just adapted to the sound system of the Chinese language?
The Wikipedia article on the Hui people has a language section, but it doesn't mention anything of this nature.
