Could you give information about Muhammad's character and high morality as evidence of his Prophethood?

Muhammad was the humblest at the zenith of his achievements

• If a man’s world-admired accomplishments or the wealth and fame he has gained do not change him, if he can remain as humble as he was at the beginning of his career, this shows that person’s strength of character, morality and virtue. Despite his unparalleled achievements, the Prophet Muhammad, was poorer and more humble when he entered Makka victoriously than he was at the beginning of his mission.

Those who saw the Messenger would say: ‘One with such a face cannot lie’

• One’s face reveals one’s inner world and character. Those who saw the Prophet Muhammad could not help but admire his appearance and, if they were unprejudiced, acknowledge his truthfulness. For example, Adbullah ibn Salam, the most renowned Jewish scholar of the time, believed in him at his first sight of him, saying: ‘One with such a face cannot lie.’
• If a fire-fly claimed that it is the sun, its lie could last only until the sun rises. Turkish people say that a liar’s candle only burns till bedtime, meaning that a lie has only a very short life. So, a deceitful one pretending Prophethood will soon be discovered and no one will accept him as a true Prophet.

Muhammad’s utmost conviction of his cause, together with his sincerity and solemnity prove his Prophethood

• Even an insignificant man of small standing, in a small group in a disputed matter of little importance, cannot tell a small but shameful lie openly and comfortably without displaying such anxiety and uneasiness as will make his enemies aware of his deception. Since the Prophet Muhammad challenged everybody to come until the Last Day and uttered many important speeches in a large community concerning a great cause, with great ease and freedom, without hesitation or anxiety, with pure sincerity and great solemnity, and in an intense and elevated manner that provoked his enemies, it means that he was certainly a Prophet speaking whatever God revealed to him.

Despite being unlettered, the Prophet Muhammad spoke on every issue and has not been contradicted ever since

• It is impossible for an unlettered one to speak on a matter requiring expert knowledge, especially before those with specialized knowledge of that matter. However, despite being unlettered, the Prophet Muhammad, upon him be peace and blessings, spoke on every issue from theology and metaphysics to medicine, history, physics and biology and has not been contradicted ever since. Besides, when he was raised up as a Prophet, the arts of literature, eloquence and oratory were at their peak and the Qur’an he received from God challenged all of its opponents to bring the like of a single chapter of its but no one has ever been able to do that.

Muhammad had to confront all kinds of hardships and persecutions after Prophethood and spent for his cause whatever he had

• For the sake of a deception no one risks his life, wealth and reputation and bears great hardships and persecutions unless he has great aspirations to more wealth and great worldly positions. Before claiming Prophethood, the Prophet Muhammad, upon him be peace and blessings, was well off and had a respected place among his community. However, he had to confront all kinds of hardships and persecutions after Prophethood and spent for his cause whatever he had. His enemies slandered him, mocked him, beat him, expelled him from his homeland and waged war on him. He bore all such cruel treatments and hostilities without complaint and asked God Almighty for the forgiveness of even his enemies. The only cause he pursued was to see everybody believing in and worshipping the One God exclusively and thereby prosperous in both worlds and saved from the torments of Hell.

Prophet Muhammad practiced with utmost sincerity and honesty what he communicated to others

• History has witnessed many leading persons who, since they themselves did not practice what they preached or propagated, did not have a large devoted following. Their ideas did not have an enduring effect on people and the systems they established did not last long. However, the Prophet Muhammad practiced with utmost sincerity and honesty what he communicated to others and was always the first and foremost in obedience to the religion he brought, in worship to the Creator and in avoidance of the religious prohibitions. This shows his full conviction of his cause and that he is a Messenger of God, Who sent him to humanity to guide them to the True Path.
  
  For what reason other than conveying God’s Message to people must he have endured all kinds of hardships and persecutions, such as sleeping on earth, suffering hunger for several consecutive days, spending a considerable part of his life on battlefields and military campaigns, being expelled from his homeland, becoming subject to mockeries and insults?
• Man acquires an established character until he is thirty and especially after thirty a man’s character does not change. Particularly, it is very difficult for one to change his temper and disposition after he is forty. If—God forbid such a thought!— there had been any imperfection and blemish in the character of Muhammad, upon him be peace and blessings, it would certainly have appeared before his Prophethood. Therefore, no one with a bit of intelligence and fairness, unless he is prejudiced, can accept that one who was never heard tell a lie and witnessed deceive until one was forty, would appear as the worst, meanest trickster of human history after forty.

A lying, deceitful one cannot have a large, dedicated following who are ready to sacrifice themselves for him

• A lying, deceitful one cannot have a large, dedicated following who are ready to sacrifice themselves for him. Despite being among the five greatest Prophets, Moses and Jesus did not have followers as devoted as Muhammad’s Companions. The followers of Moses betrayed him when he left them for forty days to receive the Torah on Mount Sinai, and began to worship a golden calf which Samiri made for them. Even after so many years of intellectual and spiritual training in the desert, except for two God-fearing men, they did not obey his order to fight against the Amalekites, the people of Goliath. As for Jesus, upon him be peace, one of his most devoted twelve followers betrayed him and attempted to submit him to his enemies. But the followers of Muhammad, upon him be peace and blessings, known as the Companions, were so devoted to him that they sacrificed for him their lives and properties. Although brought up among a primitive people and in a climate of ignorance, devoid of any positive notions of social life and administration, without a Scripture and immersed in the darkness of the uncivilized era after the Prophets, in a very short period, they became in the footsteps of their exalted leader, the Prophet Muhammad, the masters, guides and just rulers of the most civilized and socially and politically advanced peoples and states, and ruled the world from east to west in a world-admired fashion.
  
  Also, innumerable exacting and profound scholars and world-famous scientists and pure, spiritual masters were brought up among the succeeding generations following the Companions. The civilization they established was the most magnificent one history has ever known. Is it conceivable, then, that all those most shining stars of human history followed a lying, deceitful one? God forbid such a thought!

His teacher was God

• The Prophet Muhammad appeared in the heart of a desert which was almost the most uncivilized part of the then inhabited world and where people were immersed in the worst kinds of immorality. He had lost his father while he was yet in the womb of his mother. When his mother died, he was only six years old. It was impossible for his grandfather and uncle to bring him up as the most virtuous of all times. His teacher was God, as he himself said: My Lord educated me and taught me good manners, and how well he educated me and how beautifully He taught me good manners!

No one in human history has ever been able to combine in himself all of the virtues and good qualities as perfectly as the Prophet Muhammad

• Human history has seen many virtuous persons. However, no one has ever been able to combine in himself all of the virtues and good qualities as perfectly as the Prophet Muhammad, upon him be peace and blessings. There have been many generous people but they have not been able to show enough courage when and where necessary. Likewise, there have been many courageous people, who have not been able to be lenient and generous at the same degree. But the Prophet Muhammad combined in his person all the virtues and laudable qualities at the highest level.

The Prophet Muhammad was perfectly balanced in his virtues and good moral qualities

• The Prophet Muhammad was perfectly balanced in his virtues and good moral qualities. He was perfectly courageous where to show courage was necessary, while he was perfectly mild, forgiving and humble among people. He was perfectly dignified but also very gracious. There was no one more generous than him but he was also thrifty and condemned extravagance. In short, all virtues and good qualities existed in him in a well-balanced combination.

Prophet Muhammad had all of the essential attributes pertaining to Prophets

• According to theologians, there are six essentials of Prophethood common to all of the Prophets. They are truthfulness, trustworthiness, communication of God’s commands, intelligence, infallibility and being free from all kinds of bodily and mental defects. History is a witness that the Prophet Muhammad, upon him be peace and blessings, had all of these six essential attributes in a most perfect fashion.

Muhammad’s achievements are unparalleled in history

• A man encounters in his life many situations where he must make decisions with no delay and hesitation. Many decisions made in such situations may cause him great difficulties. The Prophet Muhammad, upon him be peace and blessings, made so great achievements in so short a time as 23 years that they are unparalleled in human history. He never faltered and all of his decisions proved to be true.
  
  More than that, whatever he did and whatever he said did not concern only his own time but he addressed all times and places and all peoples and levels throughout the world to come until the Last Day. Is it possible for one who is not a Prophet taught by God, the All-Knowing, to have such intelligence, foresight, sagacity, insight, sound reasoning and prudence?
