This paper deals with some difficult problems in the early stages of the history of medieval Chinese-Arab relations. Mainly limited to three problems; the first is whether the Islamic prophet Muhammad (PBUH) sent envoys to China. The 2nd is the authenticity of the well-known statement in Arab history and the hadith that is generally popular among Chinese Muslims and academic circles: "Seek knowledge even if you have to go as far as China"? The 3rd is, when was Islam introduced to China? It can be said that these and other related topics till now have not reached a convincing answer in the history of Sino-Arab relations since ancient times, especially the problem of the introduction of Islam into China. The main reason for picking these three questions is that Chinese scholars and even Arab scholars have been searching for answers from a historical perspective. Of course, this approach is logical. However, at least as far as I know, previous scholars did not enough cite Arabic historical documents and linguistics to explore the answer. In addition, this small paper also provides novel ideas for senior scholars, that is, to explore the answer to this topic by combining bilaterally related historical documents and linguistics. For this reason, the author first discusses these three topics in the traditional way and then uses the logical development of historical events and the meaning embedded in the language to solve and provide fresh viewpoints and conclusions.
  本小论文讲述中世纪中国阿拉伯关系史初期的一些难题。主要限于三个难题；第一是伊斯兰圣人穆罕默德是否向中国派遣使节。第二是，在阿拉伯历史上较为著名的说法乃至中国穆斯林和学术界普遍流行的圣训：“学问，哪怕远在中国亦当求之"的真实性？第三是，伊斯兰何时传入中国？。
 可以说，这些等相关话题在中阿关系史上自古以来是至今还没达到一个可说服力的答案，尤其是伊斯兰传入中国的这个难题。挑这些三个问题的主要原因是这些问题一直以来是中国学者乃至阿拉伯学者也罢从历史角度去深入搜求答案。当然这个方法是与理相符。可是，最起码据我所知，前辈学者没有引用阿拉伯历史文献和语言学去探究答案。另外，本小论文也向前辈学者能提供新颖的思路，也就是将双边相关的历史文献和语言学来探究本话题的答案。为此，笔者先依靠传统的方式来论述这些三个话题后，再以历史事件的逻辑发展及其语言所内藏的含义来解决并提供新鲜的观点和结论。
在本论文当中我们主要论述了两个大问题，第一是，伊圣人在世期间是否与中国建立外交关系，或者说，是否向中国派遣了使节？第二是，‘求学问，哪怕远在中国亦当求之'的圣训真相？实际上，在回答此两个问题之前，必定先讨论若干相关其他问题，比如：圣人在世期间是否听到过中国？若是，那他有没有联系过中国？如果联系了，此种联系的情形如何？在本论文中，笔者力图回答此类等相关问题。
