The Bible reports that Jesus Christ  offered the following logical criteria for distinguishing true prophets from false ones:

Beware of false prophets, who come to you in sheep’s clothing, but inwardly they are ravenous wolves. You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles? Even so, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Therefore, by their fruits you will know them.47

The Prophet Jesus  may have intended by these “fruits” that actions speak louder than words about a person’s character, and therefore the personal conduct of a true prophet must be good. He may have also intended that the positive impact of his teachings on others will be good, or that the message itself must be a clear call to purity and goodness. The beauty of analyzing the ministry of Muhammad صلى الله عليه وسلم is that all three interpretations would stand true for him. The following three chapters will illustrate how his character, his accomplishments, and his message all make a powerful case for his prophethood— beginning with his character in this chapter.

God combined in Muhammad صلى الله عليه وسلم the most illustrious qualities, as evidence that he was in fact authorized by the Divine. His character sparkled from every angle, and this was noticed both by those who experienced him firsthand and those who later read his biography. They all found in Muhammad صلى الله عليه وسلم a lifestyle of extraordinary sincerity, conviction, and virtue that posed a formidable challenge to any doubter in his prophethood. As Ibn Taymīyah (d. 1328), an eminent Muslim theologian, said, It is known that someone who claims to be a prophet is either one of the best and noblest of the creation, or the worst and most wicked of them … so how could there ever be any confusion between the best and noblest and between the worst and most wicked? … There has never been any liar who claimed prophethood except that his ignorance, dishonesty, wickedness, and devilish ways became clear to anyone who possessed the smallest degree of discernment.48

A person may wonder about the historical reliability of the reports in the following pages, and why trust that these are anything more than pious exaggerations by Muhammad’s صلى الله عليه وسلم admirers on the greatness of his character. This concern will be revisited in greater detail amidst the discussion on miracles, but let us cite here the testimony of two non-Muslim historiographers who specialized in the traceability of Islam’s prophetic traditions. David S. Margoliouth (d. 1940), the famous English Orientalist, said regarding the isnād system in Islamic scholarship, which requires that reports only be transmitted through a rigorously scrutinized chain of narrators, …its value in making for accuracy cannot be questioned, and the Muslims are justified in taking pride in their science of tradition. In other ancient records, we have to take what is told on the author’s assertion: it is rare that a Greek or Roman historian tell us the source of his information…49 Even a staunch Orientalist like Bernard Lewis (d. 2018), who was a sharp critic of Islam and Muslims in modern times, acknowledged the strength of the Hadith tradition. The British- American historiographer wrote, But their careful scrutiny of the chains of transmission and their meticulous collection and preservation of variants in the transmitted narratives give to medieval Arabic historiography a professionalism and sophistication without precedent in antiquity and without parallel in the contemporary medieval West. By comparison, the historiography of Latin Christendom seems poor and meagre, and even the more advanced and complex historiography of Greek Christendom still falls short of the historical literature of Islam in volume, variety and analytical depth.50

The following pages will demonstrate how even a brief overview of Muhammad’s صلى الله عليه وسلم character not only refutes the oft-recycled charges leveled against him—being an imposter prophet or a ruthless warlord—but also establishes the truth of his claim that he was God’s final prophet to the world.
