Alphonse de Lamartine
“Philosopher, orator, apostle, legislator, warrior, conqueror of ideas, restorer of rational dogmas, the founder of twenty terrestrial empires and of one spiritual empire, that is Muhammad. As regards all standards by which human greatness may be measured, we may ask, is there any man greater than he?” (History of Turkey)
“If greatness of purpose, smallness of means, and astonishing results are the three criteria of a human genius, who could dare compare any great man in history with Muhammad?” (History of Turkey)
Arthur Glyn Leonard
“If ever any man on this earth has found God; if ever any man has devoted his life for the sake of God with a pure and holy zeal then, without doubt, and most certainly that man was the Holy Prophet of Arabia.” (Islam Her Moral and Spiritual Value: a Rational and Pyschological Study)
“It was the genius of Muhammad, the spirit that he breathed into the Arabs through the soul of Islam that exalted them. That raised them out of the lethargy and low level of tribal stagnation up to the high watermark of national unity and empire. It was in the sublimity of Muhammad’s deism, the simplicity, the sobriety and purity it inculcated the fidelity of its founder to his own tenets, that acted on their moral and intellectual fiber with all the magnetism of true inspiration.” (Islam Her Moral and Spiritual Value: a Rational and Pyschological Study)
“Muhammad was, to use a striking expression, the man of the hour…
When Christianity conquered Caesarism at the commencement of the fourth century, it, in its turn, became Caesarised. No longer was it the pure creed which had been taught some three centuries before. It had become largely de-spiritualised, ritualised, materialised …….
How, in a few years, all this was changed, how, by 650 AD a great part of this world became a different world from what it had been before, is one of the most remarkable chapters in human history …. This wonderful change followed, if it was not mainly caused by, the life of one man, the Prophet of Mecca ….
Whatever the opinion one may have of this extraordinary man, … there can be no difference as to the immensity of the effect which his life has had on the history of the world.” (Arabian Society at the Time of Muhammad)
“If the object of religion be the inculcation of morals, the diminution of evil, the promotion of human happiness, the expansion of the human intellect, if the performance of good works will avail in the great day when mankind shall be summoned to its final reckoning it is neither irreverent nor unreasonable to admit that Muhammad was indeed an Apostle of God.”
(History of the Moorish Empire in Europe)
Michael H. Hart
“My choice of Muhammad to lead the list of the world’s most influential persons may surprise some readers and may be questioned by others, but he was the only man in history who was supremely successful on both the religious and secular levels.”
“Of humble origins, Muhammad founded and promulgated one of the world’s great religions, and became an immensely effective political leader. Today, thirteen centuries after his death, his influence is still powerful and pervasive.”
(In his book “The 100”, Michael Hart ranks Holy Prophet Muhammad (peace and blessings of Allah be upon him) as the most influential person in human history)
“Muhammad had to start virtually from scratch and work his way towards the radical monotheistic spirituality of his own. When he began his mission, a dispassionate observer would not have given him a chance. The Arabs, he might have objected, were just not ready for monotheism: they were not sufficiently developed for this sophisticated vision. In fact, to attempt to introduce it on a large scale in this violent, terrifying society could be extremely dangerous and Muhammad would be lucky to escape with his life.
Indeed, Muhammad was frequently in deadly peril and his survival was a near-miracle. But he did succeed. By the end of his life he had laid an axe to the root of the chronic cycle tribal violence that afflicted the region and paganism was no longer a going concern. The Arabs were ready to embark on a new phase of their history.” (Muhammad – A Biography of the Prophet)
Sir William Muir
“It is strongly corroborative of Mohammad’s sincerity that the earliest converts to Islam were not only of upright character, but his own bosom friends and people of his own household who, intimately acquainted with his private life could not fail otherwise to have detected those discrepancies which even more or less exist between the profession of the hypocritical deceiver abroad and his actions at home.” (The Life of Mohammad)
Rev. Bosworth Smith
“Head of the state as well as the Church, he was Caesar and Pope in one, but he was Pope without the Pope’s pretensions, and Caesar without the legions of Caesar, without a standing army, without a body guard, without a palace, without a fixed revenue. If ever a man had the right to rule by a right divine, it was Muhammad for he had all the power without the instruments and without its supports.” (Muhammad and Muhammadanism)
