Muslims are present in our cities and neighborhoods in growing numbers, and the opportunity for gospel witness is real. Even the sensitive subject of Muhammad is not off-limits—it simply requires wisdom. Muslims today are questioning their faith at an unprecedented rate, in part because information once accessible only to specialists is now available to anyone with a smartphone. Here are three principles to guide your conversations.

Muhammad is the most important human figure for the world’s approximately two billion Muslims.¹ They regard him as the final prophet sent by their deity, Allah, to proclaim truth and provide guidance to all of humankind. According to Islamic teaching, Allah revealed his word through many prophets and messengers throughout history—but the greatest and ultimate revelation came through Muhammad, whose message surpasses and supersedes all earlier ones. Ultimately, Islam rests on two foundational pillars: Allah’s word and Allah’s messenger—the Quran and Muhammad, respectively. Muslims understand Allah’s word as perfectly embodied in the life of Allah’s final prophet; to comprehend the message, observe the man who delivered it. Muhammad, for Muslims, is at once the vessel of divine revelation and the exemplary model of its application. He is, in every sense, central to the faith.

Despite his towering importance, however, most Muslims possess only a conventional knowledge of his life. Many details remain hazy or unknown even to the devout. For non-Muslims, the gap is wider still. So where can people turn to learn more about Muhammad?

Reliable resources are surprisingly few. The Quran itself mentions Muhammad by name only four times and provides no biographical detail (Q 3:144; 33:40; 47:2; 48:29). The Muslim sources that do offer detail—recording Muhammad’s deeds, sayings, and character—contain apparent discrepancies and contradictions, and all were composed at least two centuries after his presumed death.

So, what do we actually know? Who was Muhammad to his followers and to his contemporaries? Did he truly exist? What did he teach? This essay examines these questions by distinguishing three figures: the Muhammad of tradition, the Muhammad of legend, and the Muhammad of history. After considering this, we’ll reflect on how Christians might wisely speak to Muslims about their leader.

The Muhammad of Tradition

According to Muslim tradition, Muhammad was born in Mecca around 570 and died in Medina in 632. Both cities are in modern-day Saudi Arabia. His father, Abdullah, died four months before his birth.

Tradition also surrounds his arrival with remarkable signs. His mother, Amina, reportedly experienced no labor pain. At the moment of his birth, a celestial light filled the room. A mansion in Persia—roughly a thousand miles away—shook violently and fourteen of its pillars collapsed. Even the sacred fire of Persia, said to have burned continuously for a millennium, was mysteriously extinguished.

These traditions were composed by Muslim scholars of the Abbasid caliphate, writing centuries after Muhammad’s lifetime. Their evident purpose was to present Islam’s prophet to the Christians and Jews living under Muslim rule in the expanding caliphate. The reasoning follows an implicit logic: if miraculous signs attended the births of Moses and Jesus, surely Muhammad’s advent warranted them as well. This argument, however, creates a tension within Islamic teaching itself—the Quran insists that the only miracle Muhammad ever performed was the Quran (Q 6:37; 11:12; 13:7; 28:48; 29:50–51).

In matters of character and vocation, tradition portrays Muhammad as a shepherd and trader known among the Meccans as “The Honest” and “The Trustworthy.” A wealthy widow named Khadija hired him, fell in love with him, and proposed marriage, despite being fifteen years his senior. Tradition also holds that Muhammad never participated in the polytheistic idol worship of his people. He inclined always toward the worship of one God, retreating regularly to a mountain cave on the outskirts of Mecca to pray and meditate.

When he was forty, tradition says, the angel Gabriel appeared to him and declared that Allah had chosen him as a prophet with a single, clarifying message: there is only one deity, Allah. This strict monotheism—the absolute oneness of the deity, with no plurality or partners—became the cornerstone of Islamic proclamation. After initial hesitation, Muhammad began preaching quietly among his relatives. When his monotheistic message became known, persecution followed. For thirteen years, he and his small band of followers endured harassment and suffering at the hands of Mecca’s powerful pagan establishment.

Eventually, Allah instructed Muhammad and his followers—a group of roughly thirty men—to emigrate northward to Medina, an oasis city where they could practice their faith without reprisal. In Medina, Muhammad’s fortunes changed dramatically. He grew in power, became a statesman and commander, and began launching military campaigns against three groups: Arab pagans in western Arabia, Jewish communities in and around Medina, and Christian tribes along the Byzantine frontier in Greater Syria. Muslim historians portray him as a highly successful military leader, guided and aided by Allah, who killed enemies, seized lands, claimed possessions, and extended the reach of the new religion. This militarized portrait may seem jarring to modern sensibilities, but it is the portrait Muslim historians themselves advanced—apparently intent on depicting a prophet whose divine favor was demonstrated through earthly conquest and accumulated power.

In one of these campaigns, tradition reports, a Jewish woman whose father, brother, and uncle Muhammad had killed invited him to share a meal. Surprisingly he agreed. She poisoned the lamb she served him. Though he survived the immediate effects, Muslim sources identify this poisoning as the ultimate cause of his death—the toxin, they claim, lingered in his blood for four years before it finally claimed his life, thus allowing him to be numbered among the martyrs.

This is the traditional Muhammad—the figure who lives in the minds of religiously informed Muslims who have studied the classical sources. For this group, the details matter, and they treasure what the tradition preserves.

The Muhammad of Legend

While the traditional Muhammad derives from ancient Islamic texts—however late and however contested—the legendary Muhammad is born of popular imagination and folk piety. This is the Muhammad held by many nominal or cultural Muslims: an idealized figure who is superlative in every conceivable quality. For these Muslims, Islam is often an inherited identity rather than a studied conviction. They are Muslim because they were born into it, not because they have engaged the primary sources.
