The Quran is the only primary source for the life of Muhammad in Mecca. The text of the Quran is generally considered by university scholars to record the words spoken by Muhammad as the search for variants in Western academia has not yielded any differences of great significance. The Quran, however, mainly records the ideological and spiritual considerations of Muhammad, and only fragmentarily references to the details of his life in the city, which makes it difficult to reconstruct the chronological order of the incidents in his or his followers' lives in Mecca. Modern biographers of Muhammad try to reconstruct the socioeconomic and sociopolitical aspects of Mecca and read the ideological aspects of the Quran in that context.
