“Muhammad ﷺ wrote the Qur'an himself.”

This claim sits at the center of a genuine, serious historical and theological disagreement between Muslims and skeptics — one this site doesn’t try to paper over. Islamic tradition holds Muhammad ﷺ was ummi, generally understood as unable to read or write, which Muslims point to as significant given the Qur’an’s linguistic and structural sophistication.

Whether the Qur’an’s origin is best explained by revelation, as Muslims believe, or by human authorship, as some critics argue, is a substantive question addressed across this site — including in our Why Islam section — rather than one this short myth-format page can fully resolve. What we can say plainly here: Islamic belief is unambiguous that Muhammad ﷺ received the Qur’an rather than composed it, and that distinction is foundational to the religion, not incidental to it.
