Non-Muslim Western and Far Eastern Philosophers' opinions about Muhammad(saw) 

"He must be called the Savior 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 much needed peace and happiness." 
(The Genuine Islam, Singapore, Vol. 1, No. 8, 1936) 

He was by far the most remarkable man that ever set foot on this earth. He preached a religion, founded a state, built a nation, laid down a moral code, initiated numerous social and political reforms, established a powerful and dynamic society to practice and represent his teachings and completely revolutionized the worlds of human thought and behavior for all times to come." His Name was Muhammad" 
May Peace of God Be Upon Him (saw) 

He was born in Arabia in the year 570 C.E. (common era), started his mission of preaching the religion of Truth, Islam(submission to One God) at the age of forty and departed from this world at the age of sixty-three. During this short period of 23 years of his Prophethood, he changed the complete Arabian peninsula from paganism and idolatry to worship of One God, from tribal quarrels and wars to national solidarity and cohesion, from drunkenness and debauchery to sobriety and piety, from lawlessness and anarchy to disciplined living, from utter bankruptcy to the highest standards of moral excellence. Human history has never known such a complete transformation of a people or a place before or since - and imagine all these unbelievable wonders in just over two decades.

From my studies and from what I have learned throughout this conference, I believe that everything that has been recorded in the Qurân 1400 years ago must be the truth, that can be proved by the scientific means. Since the Prophet Muhammad(saw) could neither read nor write, Muhammad(saw) must be a messenger who relayed this truth which was revealed to him as an enlightenment by the One Who is an eligible Creator. This Creator must be Allah, or Allah. Therefore, I think this is the time to say ‘Laa ilaaha illallah’, that there is no Allah to worship except Allah, ‘Muhammad(saw) Rasool Allah’, Muhammad(saw) is messenger of Allah...

"I wanted to know the best of one who holds today's 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 this 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." 
MAHATMA GANDHI, speaking on the character of Muhammad(saw), says in (YOUNG INDIA): 
 
"Muhammad, the inspired man who founded Islam, was born about A.D. 570 into an Arabian tribe that worshipped idols. Orphaned at birth, he was always particularly solicitous of the poor and needy, the widow and the orphan, the slave and the downtrodden. At twenty, he was already a successful businessman, and soon became director of camel caravans for a wealthy widow. When he reached twenty-five, his employer, recognizing his merit, proposed marriage. Even though she was fifteen years older, he married her, and as long as she lived, remained a devoted husband. "Like almost every major prophet before him, Muhammad fought shy of serving as the transmitter of God's word, sensing his own inadequacy. But the angel commanded 'Read.' So far as we know, Muhammad was unable to read or write, but he began to dictate those inspired words which would soon revolutionize a large segment of the earth: 'There is one God.' "In all things Muhammad was profoundly practical. When his beloved son Ibrahim died, an eclipse occurred, and rumors of God's personal condolence quickly arose. Whereupon Muhammad is said to have announced, 'An eclipse is a phenomenon of nature. It is foolish to attribute such things to the death or birth of a human being. "At Muhammad's own death an attempt was made to deify him, but the man who was to become his administrative successor killed the hysteria with one of the noblest speeches in religious history: 'If there are any among you who worshipped Muhammad, he is dead. But if it is God you worshipped, He lives forever."
James A. Michener, "Islam: The Misunderstood Religion," in READER'S DIGEST (American edition), May 1955, pp. 68-70. 
 
"It is impossible for anyone who studies the life and character of the great Prophet of Arabia, who knows how he taught and how he lived, to feel anything but reverence for that mighty Prophet, one of the great messengers of the Supreme. And although in what I put to you I shall say many things which may be familiar to many, yet I myself feel whenever I re-read them, a new way of admiration, a new sense of reverence for that mighty Arabian teacher."
Annie Besant, THE LIFE AND TEACHINGS OF Muhammad(saw), Madras, 1932, p. 4. 
 
"His readiness to undergo persecutions for his beliefs, the high moral character of the men who believed in him and looked up to him as leader, and the greatness of his ultimate achievement - all argue his fundamental integrity. To suppose Muhammad(saw) an  impostor raises more problems than it solves. Moreover, none of the great figures of history is so poorly appreciated in the West as Muhammad."
W. Montgomery Watt, MUHAMMAD AT MECCA, Oxford, 1953, p. 52. 
 
My choice of Muhammad(saw) 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 level."

 It follows, I think, that not only is there no conflict between genetics and religion, but in fact religion can guide science by adding revelation to some traditional scientific approaches. That there exists statements in the Qurân shown by science to be valid, which supports knowledge in the Qurân having been derived from Allah. 

Joe Leigh Simpson, Professor of Obstetrics and Gynecology at the North Western University in Chicago in the United States of America. 

 

"It seems to me that Muhammad(saw) was a very ordinary man. He could not read or write. In fact, he was illiterate. We are talking about 1400 years ago. You have someone who was illiterate making profound pronouncement and statements and are amazingly accurate about scientific nature. I personally cannot see how this could be mere chance. There are too many accuracy’s and, like Dr. Moore, I have no difficulty in my mind in concerning that this is a divine inspiration or revelation which led him to these statements."

"Thinking about many of these questions and thinking where Muhammad(saw) came from, he was after all a Bedouin(a tribe in Middle East). I think it is almost impossible that he could have known about things like the common origin of the universe, because scientists have only found out within the last few years with very complicated and advanced technological methods that this is the case.

Professor Yushudi Kusan: Director of the Tokyo Observatory, I can say, I am very much impressed by finding true astronomical facts in the Qurân.  Professor William W. Hay is one of the best known marine scientists in the United States. satellite photography and emote-sensing techniques. Professor Hay replied: I find it very interesting that this sort of information is in the ancient scripture of the Holy Qurân, and I have no way of knowing where they would come from, but I think it is extremely interesting that they are there and that this work is going on to discover it, the meaning of some of the passages. Professor Hay: Well, I would think it must be the divine being!

"How, for instance, can any other appeal stand against that of the Moslem who, in approaching the pagan, says to him, however obscure or degraded he may be 'Embrace the faith, and you are at once equal and a brother.' Islam knows no color line."

"The founder of twenty terrestrial empires and of one spiritual empire, that is Muhammad(saw). As regards all standards by which human greatness may be measured, we may well ask, is there any man greater than he?

"It (Islam) replaced monkishness by manliness. It gives hope to the slave, brotherhood to mankind, and recognition of the fundamental facts of human nature."

I am impressed that how remarkably some of the ancient writings seem to correspond to modern and recent Astronomy. There may well have to be something beyond what we understand as ordinary human experience to account for the writings that we have seen.

"No other society has such a record of success in uniting in an equality of status, of opportunity and endeavor so many and so varied races of mankind. The great Muslim communities of Africa, India and Indonesia, perhaps also the small community in Japan, show that Islam has still the ower to reconcile apparently irreconcilable elements of race and tradition. If ever the opposition of the great societies of the East and west is to be replaced by cooperation, the mediation of Islam is an indispensable condition."
 H.A.R. Gibb, WHITHER ISLAM, p. 379
 
"I have read the Sacred Scriptures of every religion; nowhere have I found what I encountered in Islam: perfection. The Holy Qurân, compared to any other scripture I have read, is like the Sun compared to that of a match. I firmly believe that anybody who reads the Word of Allah(swt) with a mind that is not completely closed to Truth, will become a Muslim."
Saifuddin Dirk Walter Mosig, U.S.A. 
 
"Everything made so much sense. This is the beauty of the Qurân; it asks you to reflect and reason....When I read the Qurân further, it talked about prayer, kindness and charity. I was not a Muslim yet, but I felt the only answer for me was the Qurân and God had sent it to me."
 Cat Stevens (Yusuf Islam), former British pop star. 
 
"Muhammad(saw) was the soul of kindness, and his influence was felt and never forgotten by those around him."

"People like Pasteur and Salk are leaders in the first sense. People like Gandhi and Confucius, on one hand, and Alexander, Caesar and Hitler on the other, are leaders in the second and perhaps the third sense. Jesus and Buddha belong in the third category alone. Perhaps the greatest leader of all times was Muhammad(saw), who combined all three functions. To a lesser degree, Moses did the same."
Professor Jules Masserman 
 
"Sense of justice is one of the most wonderful ideals of Islam, because as I read in the Qurân I find those dynamic principles of life, not mystic but practical ethics for the daily conduct of life suited to the whole world."

"The extinction of race consciousness as between Muslims is one of the outstanding achievements of Islam, and in the contemporary world there is, as it happens, a crying need for the propagation of this Islamic virtue."

"The closer we examine this development the more extraordinary does it appear. The other great religions won their way slowly, by painful struggle and finally triumphed with the aid of powerful monarchs converted to the new faith. Christianity had its Constantine, Buddhism its Asoka, and Zoroastrianism its Cyrus, each lending to his chosen cult the mighty force of secular authority. Not so Islam. Arising in a desert land sparsely inhabited by a nomad race previously undistinguished in human annals, Islam sallied forth on its great adventure with the slenderest human backing and against the heaviest material odds. Yet Islam triumphed with seemingly miraculous ease, and a couple of generations saw the Fiery Crescent borne victorious from the Pyrenees to the Himalayas and from the desert of Central Asia to the deserts of Central Africa."
A.M.L. Stoddard, quoted in ISLAM - THE RELIGION OF ALL PROPHETS, Begum Bawani Waqf, Karachi, Pakistan, p. 56
 
"He was Caesar and Pope in one; but he was Pope without Pope's pretensions, Caesar without the legions of Caesar: without a standing army, without a bodyguard, without a palace, without a fixed revenue; if ever any man had the right to say that he ruled by the right divine, it was Mohammad, for he had all the power without its instruments and without its supports."
Bosworth Smith, MOHAMMAD AND MOHAMMADANISM, London, 1874, p. 92. 
 
'I believe in One God and Mohammed the Apostle of God,' is the simple and invariable profession of Islam. The intellectual image of the Deity has never been degraded by any visible idol; the honors of the prophet have never transgressed the measure of human virtue, and his living precepts have restrained the gratitude of his disciples within the bounds of reason and religion."
Edward Gibbon and Simon Ocklay, HISTORY OF THE SARACEN EMPIRE, London, 1870, p. 54. 
 
"The essential and definite element of my conversion to Islam was the Qurân. I began to study it before my conversion with the critical spirit of a Western intellectual ...There are certain verses of this book, the Qurân, revealed more than thirteen centuries ago, which teach exactly the same notions as the most modern scientific researches do. This definitely converted me."
