According to Muslim tradition, the recitations comprising the Qur’an were compiled in book form only after Muhammad’s death. Western scholars wish the compilers had ordered the recitations chronologically, but they did not. We also wish the Qur’an were rich in details identifying the situations its recitations addressed, so we might accurately determine the chronological order of its suras, or chapters, to better understand them. But they only allude to those situations.
Early Muslim scholars assigned some passages to events in Muhammad’s prophetic career—the “occasions of the revelation” (asbab al-nazul). But the scholars disagreed over the occasions of certain passages and many of the events cited are minor and have no known date. The scholars also listed the suras in chronological order, divided into two periods, Meccan (610-22 CE) and Medinan (622-32). But four points are noteworthy in this respect.
First, the scholars’ primary motivation was legal, to determine which command on a given topic came given last, since they gave the final command the power to abrogate earlier ones. This meant their legal concerns were paramount when they determined the suras’ order. Second, the scholars disagreed over the placement of 23 out of the Qur’an’s 114 suras, as well as on which verses in the Meccan and the Medinan suras were out-of-period insertions. Third, there are also discrepancies between duplicate lists from the same scholar, as recorded by other scholars.
Last, while most Muslims today accept a slightly modified version of the order given by Ibn cAbbas (d. 688), that has more to do with the power of the printing press, than the power of any arguments for his order’s reliability. For the editors of the world’s most widely sold Qur’an, the Egyptian standard edition of 1924, put Ibn cAbbas’s chronological placement (slightly modified) in each sura’s heading.
Hence, though most Western scholars begin with the traditional Muslim chronology, they question its accuracy and modify it in various ways.
For example, Western chronologies take a sura’s style and contents into consideration, something Muslim chronologies do not do. The chronology of Theodore Nöldeke (d. 1930), based on that of Gustav Weil (d. 1889) and revised by Friedrich Schwally (d. 1919), takes the short suras characterized by exalted poetry to be early, and the longer, more prosaic suras to be late. Nöldeke also believed the use of al-Rahman within a sura marked it as Meccan. Nöldeke’s chronology divided the Meccan suras into three periods, showing a progression in the recitations from sublime enthusiasm to calm. Although the Nöldeke-Schwally chronology allows for some out-of-period passages, it otherwise takes the sura to be a unit.
By contrast, some Western chronologies—Richard Bell’s, for exampleçview the Qur’an’s longer suras as composites of unrelated shorter passages, given at different times. As a result, Bell’s chronology jumps from one passage to another, across the various suras. Recent studies, however, have argued on the basis of stylistic features for each sura’s unity, suggesting that it is from one period of time, whether or not it was originally delivered in one sitting.
While most Western scholars rely on the Nöldeke-Schwally chronology, others argue that there are too many gaps in our knowledge for us to have a precise chronology. Both are right.
No chronology is more than an educated guess, especially with respect to the order of the Meccan suras. Two things, however, tell us not to dismiss questions concerning chronology:
- We all come to the Qur’an with some chronological sequence in mind, however tentative—or unacknowledged. Indeed, without a rudimentary chronology, the Qur’an becomes a hopeless muddle.
- Given the gaps in our knowledge, we all work with an approximate Qur’an sequence. Nevertheless, not all approximations are equal: a well thought out approximation is far better than a poorly thought out one.
The Nöldeke-Schwally chronology can doubtless be improved upon. Nevertheless, it has established itself among Western scholars as “a rule of thumb for the approximate order of the sūras in their chronological sequence.” And interpreting the Qur’an in accord with this chronology is far more productive than simply decrying the many lamentable gaps in our knowledge.
