script The main Islamic source on Muhammad's life are the
Quran and accounts of Muhammad's life based on
oral traditions known as
sīra and
hadith.
Historicity of the Quran Islamic narrative , dated to the early 9th century. It is alleged to be a 7th-century original of the edition of the third caliph, Uthman. It is located in the small Telyashayakh mosque in
Tashkent. According to traditional Islamic scholarship, all of the Quran was written down by Muhammad's
companions while he was alive (during CE 610–632), but it was primarily an orally related document. Following the death of Muhammad the Quran ceased to be revealed, and companions who had memorized the Quran began to die off (particularly after the
Battle of Yamama in 633). Worried that parts of the Quran might be irretrievably lost, senior companion
Umar urged Caliph
Abu Bakr to order the collection of the pieces of the Quran which had hitherto been scattered among "palm-leaf stalks, thin white stones, ... [and] men who knew it by heart, ..." and put them together. Under Caliph
Uthman, a committee of five copied the scraps into a single volume, "monitoring the text as they went", resolving disagreements about verses, tracking down a lost verse. This
muṣḥaf – that became known as the "Uthmanic codex" – was finished around 650 CE, whereupon Uthman issued an order for all other existing personal and individual copies and dialects of the Quran (known as
Ahruf) to be burnt.
Modern scholarship on the Quran As to the historicity of the Quran itself, some scholars also disagree. Some argue "the Quran is convincingly the words of Muhammad" (
F.E. Peters), with the parchment of an early copy of Quran – the
Birmingham manuscript, whose text differs only slightly to modern versions – being dated to roughly around the lifetime of Muhammad. Some Western scholars, however, question the accuracy of some of the Quran's historical accounts and whether the holy book existed in any form before the last decade of the seventh century (
Patricia Crone and
Michael Cook); and/or argue it is a "cocktail of texts", some of which may have been existent a hundred years before Muhammad, that evolved (
Gerd R. Puin), or was redacted (J. Wansbrough), to form the Quran. A group of researchers explores the irregularities and repetitions in the Quranic text in a way that refutes the traditional claim that it was preserved by memorization alongside writing. According to them, an
oral period shaped the Quran as a text and order, and the repetitions and irregularities mentioned were remnants of this period. It is also possible that the content of the Quran itself may provide data regarding the date and probably nearby geography of writing of the text. Sources based on some archaeological data give the construction date of
Masjid al-Haram, an architectural work mentioned 16 times in the Quran, as 78 AH an additional finding that sheds light on the evolutionary history of the Quranic texts mentioned, which is known to continue even during the time of
Hajjaj, in a similar situation that can be seen with
al-Aksa, though different suggestions have been put forward to explain. These structures, -expected to be somewhere near Muhammad- which were placed in cities like Mecca and Jerusalem, which are thousands of kilometers apart today, with interpretations
based on narrations and miracles, were only a night walk away according to the outward and literal meaning of the verse.
Muhammad in the Quran The Quran primarily addresses a single "Messenger of God," Muhammad. Unlike the hundreds of references in the Quran to the stories of prophets such as Moses and Jesus, provides very little information about Muhammad himself,
his companions, Modern scholars differ in their assessment of the Quran as a historical source about Muhammad's life. According to the
Encyclopedia of Islam, the "Qur'an responds constantly and often candidly to Muhammad's changing historical circumstances and contains a wealth of hidden data that are relevant to the task of the quest for the historical Muhammad."
Traditions . The "subtexts" revealed using UV light are very different from today's Qur'an.
Gerd R. Puin believed this to mean an evolving text. A similar phrase is used by
Lawrence Conrad for
biography of Muhammad. Because, according to his studies, Islamic scientific view on the date of birth of the Prophet until the second century A.H. had exhibited a diversity of 85 years. In the
sīra literature, the most important extant biography are the two recensions of
Ibn Ishaq's (d. 768), now known as
Sīrat Rasūl Allah ("Biography/Life of the Messenger/Apostle of Allah"), which survive in the works of his editors, most notably
Ibn Hisham (d. 834) and Yunus b. Bukayr (d.814–815), although not in its original form.
Henri Lammens complains of contradictions in the Traditions about Muhammad's life, including on the number of his children and wives. Some accounts have him having one child, others two, and still another claimed he had twelve children, including eight boys. While most accounts state he had nine wives, "some passages of the sira speak of twenty three wives." According to Wim Raven, it is often noted that a coherent image of Muhammad cannot be formed from the literature of sīra, whose authenticity and factual value have been questioned on a number of different grounds. He lists the following arguments against the authenticity of sīra, followed here by counter-arguments: • Hardly any sīra work was compiled during the first century of Islam. Fred Donner points out that the earliest historical writings about the origins of Islam first emerged in 60-70 AH, well within the first century of Hijra (see also
List of biographies of Muhammad). Furthermore, the sources now extant, dating from the second, third, and fourth centuries AH, are according to Donner mostly compilations of material derived from earlier sources. • The many discrepancies exhibited in different narrations found in sīra works. Yet, despite the lack of a single orthodoxy in Islam, there is still a marked agreement on the most general features of the traditional origins story. • Later sources claiming to know more about the time of Muhammad than earlier ones (to add embellishments and exaggeration common to an oral storytelling tradition). • Discrepancies compared to non-Muslim sources. But there are also similarities and agreements both in information specific to Muhammad, and concerning Muslim tradition at large. • Some parts or genres of sīra, namely those dealing with miracles, are not fit as sources for scientific historiographical information about Muhammad, except for showing the beliefs and doctrines of his community. Nevertheless, other content of sīra, like the
Constitution of Medina, is generally considered to be authentic by both Muslim and non-Muslim historians. Unlike the Quran, hadiths are not universally accepted by Muslims. Early
Muslim scholars were concerned that some hadiths (and sīra reports) were fabricated, and thus they developed a science of hadith criticism (see
Hadith studies) to distinguish between genuine sayings and those that were forged, recorded using different words, or were wrongly ascribed to Muhammad. In general, the majority of western academics view the
hadith collections with considerable caution.
Bernard Lewis states that "The collection and recording of Hadith did not take place until several generations after the death of the Prophet. During that period the opportunities and motives for falsification were almost unlimited." In addition to fabrication, the meaning of a hadith may have substantially drifted from its original telling by the time it was written down. due to the potential for
isnads, like hadith, to be fabricated. asserts that the hadith tradition is a "common sense science" or a "common sense tradition" and is "one of the biggest accomplishments in human intellectual history ... in its breadth, in its depth, in its complexity and in its internal consistency." ==Non-Muslim sources==
