How do we know who Muhammad actually was?

In short: Muhammad is one of history's most influential figures, yet the primary religious text of Islam provides almost no concrete biographical details about him. To reconstruct his life, scholars must navigate a complex web of oral traditions, later literary compilations, and non-Islamic chronicles that sometimes contradict one another.

The Qurʾān identifies Muhammad as a "messenger of God" and alludes to key events—such as the pilgrimage to the Kaʿbah in Mecca or military encounters at Badr—but it lacks specific dates and rarely mentions his contemporaries by name. Because the holy text provides such a sparse biographical sketch, historians rely on the sīrah (biography) literature. The foundational work in this genre is Muḥammad ibn Isḥāq’s Kitāb al-maghāzī, which was compiled from autonomous reports tracing back to eyewitnesses like the Prophet’s wife, ʿĀʾishah.

This reliance on later sources creates a scholarly challenge. Ibn Isḥāq’s work dates significantly after Muhammad's death, and other major biographies were not preserved until the 8th or 9th centuries. While these texts are not necessarily fabrications, they are susceptible to "accretion of popular legend." For instance, some narratives include miraculous elements—like a handful of dates miraculously feeding workers—that mirror biblical motifs involving Jesus or the Twelve Apostles, potentially designed to frame Muhammad as an equal to earlier prophets.

Despite these complexities, non-Islamic sources from the first decades after 632 provide a historical anchor. A Syriac chronicle (c. 640) and an Armenian history (c. 660) confirm the existence of an Arab prophet named Muhammad who preached and triggered Islamic conquests. However, discrepancies remain: some non-Islamic records suggest he was still alive during the invasion of Palestine in 634–640, contradicting the traditional Islamic date of his death in 632. Ultimately, while the basic scaffolding of his life is likely historical, the specific details remain a subject of intense scholarly scrutiny.

For Muslims, Muhammad serves as the ultimate role model of virtue and spirituality. His teachings are codified as the Sunnah—the practical application of his behavior—while his spiritual journey through the seven heavens (Mi'raj) represents the manifestation of divine guidance. This duality between historical inquiry and religious devotion defines how his legacy is understood today.
