Non-Muslim(Islamic) views of Muhammad(Mahomet)[P.B.U.H]
There are several peoples which they have different views. It is very difficult to list all of them but I have listed some of the renowned people names with their quotes.
The image of Muhammad(P.B.U.H) in the West
In contrast to the Islamic understanding of Muhammad, the Western image of Him remained highly negative for over a millennium and has only recently begun to change by some Christians and other Scholars.
In the early modern period, the medieval image of Muhammad continued to be promoted by a variety of Western writers. The general hostility toward Islam formed part of Martin Luther's polemic against the Roman Catholic church, and the image of Muhammad as the Antichrist appeared in Alexander Ross's introduction to his translation of the Qur'an in 1649. Apocalyptic interpretations of Muhammad continued into the 19th century in America.
The first fairly positive biography of Muhammad not based on Christian “ideology” of the medieval period was Boulainvilliers's La Vie de Mahomet (“The Life of Muhammad”), published in London in 1730. The philosopher Voltaire had a fairly positive view of him as well. In 1742 Voltaire's tragedy La Fanatisme; ou, Mohamet le prophète (“Fanaticism; or, Muhammad the Prophet”) was performed in Paris, and Goethe translated it into German in 1799. This most revered of German writers was deeply attracted to Islam and planned to write a drama on this theme but completed only the famous poem Mahomets-Gesang (“Mahomet's Singing”). In the 19th century Joseph von Hammer-Purgstall was among those who wrote dramas and novels about Muhammad. At the same time, Thomas Carlyle broke new ground in On Heroes, in which he provided a positive evaluation of the Prophet. Images of Muhammad were also used by Victor Hugo in his The Legend of the Centuries (La Légende des siècles) at a moment when Western Orientalism was turning to biographies about Muhammad based on modern historical and analytic methods.
I have removed some negative views of some Christians, Jewish, etc. because we Muslims never accept His negative views, as all the Messengers(P.B.U.T.) has not commited any sin. They spread the command of Allah. The battle They fought against non-believers in God, is to worship only one God(Allah), follow the principles of Allah, etc.... But mostly Non-Muslims scholars praised Muhammad(P.U.B.H) a lot and also said that He was the great leader of that time.
I wanted to know the best of one who holds today undisputed sway over
the hearts of millions of mankind ... I became more than convinced that it
was not the sword that won a place for Islam in those days in the scheme
of life. It was the rigid simplicity, the utter self-effacement of the
Prophet, the scrupulous regard for his pledges, his intense devotion to
his friends and followers, his intrepidity, his fearlessness, his absolute
trust in God and in his own mission. These and not the sword carried
everything before them and surmounted every obstacle. When I closed the
2nd volume (of the prophet's biography), I was sorry there was not more
for me to read of the great life. "
...He had achieved a great deal. To the pagan peoples of western Arabia he had brought a new religion which, with its monotheism and its ethical doctrines, stood on an incomparably higher level than the paganism it replaced. He had provided that religion with a revelation which was to become in the centuries to follow the guide to thought and count of countless millions of Believers. But he had done more than that; he had established a community and a well organized and armed state, the power and prestige of which made it a dominant factor in Arabia.... The modern historian will not readily believe that so great and significant a movement was started by a self-seeking imposter. Nor will he be satisfied with a purely supernatural explanation, whether it postulates aid of divine of diabolical origin; rather, like Gibbon, will he seek 'with becoming submission, to ask not indeed what were the first, but what were the secondary causes of the rapid growth' of the new faith...
D. S. Margoliouth
I regard Mohammed as a great man, who solved a political problem of appalling difficulty,-the construction of a state and an empire out of the Arab tribes. I have endeavored, in recounting the mode in which he accomplished this, to do justice to his intellectual ability and to observe towards him the respectful attitude which his greatness deserves
Alexis de Tocqueville
I studied the Quran a great deal. I came away from that study with the conviction that by and large there have been few religions in the world as deadly to men as that of Muhammad. As far as I can see, it is the principal cause of the decadence so visible today in the Muslim world and, though less absurd than the polytheism of old, its social and political tendencies are in my opinion more to be feared, and I therefore regard it as a form of decadence rather than a form of progress in relation to paganism itself.
Muhammad professed to derive from Heaven, and he has inserted in the Koran, not only a body of religious doctrines, but political maxims, civil and criminal laws, and theories of science. The gospel, on the contrary, only speaks of the general relations of men to God and to each other - beyond which it inculcates and imposes no point of faith. This alone, besides a thousand other reasons, would suffice to prove that the former of these religions will never long predominate in a cultivated and democratic age, whilst the latter is destined to retain its sway at these as at all other periods.
William Montgomery Watt
The more one reflects on the history of Muhammad and of early Islam, the more one is amazed at the vastness of his achievement. Circumstances presented him with an opportunity such as few men have had, but the man was fully matched with the hour. Had it not been for his gifts as seer, statesman, and administrator and, behind these, his trust in God and firm belief that God had sent him, a notable chapter in the history of mankind would have remained unwritten.
...Only a profound belief in himself and his mission explains Muhammad's readiness to endure hardship and persecution during the Meccan period when from a secular point of view there was no prospect of success. Without sincerity how could he have won the allegiance and even devotion of men of strong and upright characters with His Companions & Caliph? For the theist there is the further question how God could have allowed a great religion like Islam to develop on a basis of lies and deceit. There is thus a strong case for holding that Muhammad was sincere. If in some respects he was mistaken, his mistakes were not due to deliberate lying or imposture.
...I therefore do not believe that either the Bible or the Qur’an is infallibly true in the sense that all their commands are valid for all time. ... when the form of society changes in important respects some commands cease to be appropriate, though many others continue to be valid. I do, however, believe that Muhammad, like the earlier prophets, had genuine religious experiences. I believe that he really did receive something directly from God. As such, I believe that the Qur’an came from God, that it is Divinely inspired. Muhammad could not have caused the great upsurge in religion that he did without God’s blessing.
I always took the view — contrary to most previous scholars of Islam — that the Quran was not something that Muhammad had consciously produced. For long, however, I hesitated to speak of him as a prophet, because Muslims would have taken this to mean that everything in the Quran was finally and absolutely true, which was something I did not believe. More recently, however, I have said that Muhammad is a prophet comparable to the Old Testament prophets, though with a different task, namely, to bring the knowledge of God to people without such knowledge, whereas their task was mainly to criticize the conduct of those who already believed in God
George Bernard Shaw
I have always held the religion of Muhammad in high estimation because of its wonderful vitality. It is the only religion which appears to me to possess that assimilating capacity to the changing phase of existence which can make itself appeal to every age. I have studied him - the wonderful man and in my opinion far from being an anti-Christ, he must be called the Saviour of Humanity. I believe that if a man like him were to assume the dictatorship of the modern world, he would succeed in solving its problems in a way that would bring it the much needed peace and happiness: I have prophesied about the faith of Muhammad that it would be acceptable to the Europe of tomorrow as it is beginning to be acceptable to the Europe of today
