Unlike the hadith collections, which were subjected to thorough scientific scrutiny by different scholars in different places and at different times, the Muslims never subjected the Quran to any form of scientific examination. On the contrary, they are warned against it because scientific studies are based on doubts, which is unacceptable to Muslims who are not supposed to have any doubts about the Quran. It is essential in Islam not to doubt the divine origin of the Quran and its preservation by Allah himself. To boost their confidence, Muslims learn to recite this verse as evidence of Allah’s promise to protect his book from corruption:
Q. 15:9 “it is We who sent down the Qur’an and indeed, We will be its guardian”
Different authors of the Meccan and Medina verses
The Quranic verses are divided into two distinct groups: The Meccan verses, which were revealed over thirteen years when Mohammed was in Mecca, and the Medina verses, which were revealed in the last ten years of Mohammed’s life in Medina.
The difference between the two groups is so obvious and striking in both contents and style; the Meccan verses are remarkably shorter and tend to contain more unfamiliar words. As Muslims start to learn the Quran, they are told from the beginning about the differences between the two groups. They are also given an explanation for this observation: The Arabs of Medina were less eloquent than those of Mecca, so Allah lowered the level of the Quran to match their level of understanding. I accepted this explanation for decades without questioning its logic but looking at it from where I stand today it does look a very naive justification.
The Arabs in Medina spoke the same language as those in Mecca and there is no reason to believe they would have had problems in understanding the Meccan style. Besides, they were still required to learn the Meccan verses anyway just like all Muslims do. Although not convincing, the above explanation makes a good point; it would be really nice if Allah speaks to people in languages they can understand.
There is no acceptable Islamic explanation for the striking change in style between the Meccan and Medina verses. But there must be one, and I believe it is the usual explanation behind any change of style, which is change of author. The Quran had at least two different authors but probably more. The differences between the Meccan and Medina verses are glaring enough to suggest they were even authored in different time periods. Indeed, there are indications that the Quran evolved over a long period of time that could have started before Islam.
