The short answer
The Qur’an is the central early Muslim text. Manuscripts, inscriptions, non-Muslim notices and later transmitted reports contribute different kinds of evidence. Their dates and purposes matter.
A source is not just “early” or “late”
Ask about at least three dates: the event described, the composition of the work and the surviving manuscript. An eighth-century author may preserve an earlier report. An early manuscript may copy an older text. Neither possibility removes the need to show the connection.
The Qur’an is comparatively reticent about biography. It engages disputes, worship, moral responsibility and community life without repeatedly explaining the background that later readers want. Biographical and commentary traditions often supply that background, but using them to explain the Qur’an and then citing the Qur’an as independent proof of the same story can become circular.
Manuscripts answer particular questions
The Birmingham leaves contain parts of surahs 18–20. Radiocarbon testing dates the parchment, not the moment ink was applied. The university reports a parchment range of 568–645 CE at 95.4% probability. That is significant material evidence, but it is not an autograph or a complete Qur’an from a precisely known year.
The Sana’a palimpsest and other early manuscripts are studied alongside the consonantal text and recorded readings. A variant may concern spelling, grammar or wording. Describe the actual difference and its significance before announcing either perfect identity or wholesale corruption.
Reports, biographies and outside witnesses
The biography associated with Ibn Ishaq survives chiefly through later transmitters and editors, including Ibn Hisham. Major hadith compilations such as those of al-Bukhari and Muslim were assembled after the first generations. Their distance from the events is a reason to investigate their sources, not a substitute for that investigation. Shia collections have their own authorities and transmission histories.
Outside observers can corroborate that a movement existed or that certain beliefs circulated. They can also misunderstand what they describe. Hostility is neither proof of falsehood nor a guarantee of independence. Compare the detail each source can actually support.
What this establishes, and what it does not
No one kind of source supplies a complete biography or settles the theological claim. Dating a material object and dating its contents are related but distinct tasks.
