《古兰经》是穆斯林所诵读的经典。它是真主的话语，也是最后的启示，于一千四百多年前以阿拉伯语降示给先知穆罕默德ﷺ。其中没有一个字母被改动、删减或增添过，也不存在不同版本的《古兰经》。因此，在中国清真寺里所见的《古兰经》，与在南美清真寺里所诵读的《古兰经》完全相同。《古兰经》围绕三个根本性的问题展开：

The Quran is the Book read by Muslims. It is the word of God and the final revelation; sent to Prophet Muhammad (peace be upon him) in the Arabic language over 1400 years ago. Not a single letter has been altered, subtracted or added. There are not different versions of the Quran. For this reason, a Quran found in a mosque in China is the same Quran read in a mosque in South America. The Quran centers around three fundamental matters:

1. 关于安拉独一性的知识以及信条方面的事务。

1. Knowledge about the Oneness of Allah, and affairs of doctrine.

2. 命令行善，禁止作恶。

2. Commands toward good, and prohibitions from evil.

3. 关于创造的知识，包括先知及其民族的故事、创造的开端以及后世。

3. Knowledge about the creation, to include stories of the prophets and their nations, the beginning of creation, and the Afterlife.

《古兰经》的意义已被译成众多语言。最优秀、流传最广的英文译本是由希拉利博士和穆辛·汗共同翻译的《尊贵的古兰经》。

The meaning of the Quran has been translated into numerous lan guages. The best, most widely distributed, English translation is The Noble Quran, translated by Dr. Hilali and Muhsin Khan.
