One of my most remembered statement when I joined Minzu University's Islamic class for first time (and last time too, unfortunately) in 2011. He was mentioning about the Arabic class in Beijing Foreign Studies University, whereby most of its students are local non-Muslim Chinese students.
The beauty of a language lies in its holy literature. And for Arabic, it is in Quran. For non-Muslim students studying Arabic language, they will also find it in the Prophet's sayings -the Hadith, too.
