Religious texts

To complicate matters further, as with other languages, the meanings and usages of some expressions have changed over time, between the Classical Arabic of the Quran, and modern Arabic. Thus a modern Arabic speaker may misinterpret the meaning of a word or passage in the Quran. Moreover, the interpretation of a Quranic passage will also depend on the historic context of Muhammad's life and of his early community. Properly researching that context requires a detailed knowledge of hadith and sirah, which are themselves vast and complex texts. Hence, analogously to the translating of Chinese literature, an attempt at an accurate translation of the Quran requires a knowledge not only of the Arabic language and of the target language, including their respective evolutions, but also a deep understanding of the two cultures involved.
