Mahatma Gandhi, statement published in 'Young India,'1924.
I wanted to know the best of the life of one who holds today an undisputed sway over the hearts of millions of mankind.... I became more than ever 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 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 second volume (of the Prophet's biography), I was sorry there was not more for me to read of that great life.
Sir George Bernard Shaw in 'The Genuine Islam,' Vol. 1, No. 8, 1936.
"If any religion had the chance of ruling over England, nay Europe within the next hundred years, it could be Islam."“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 for from being an anti-Christ, 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 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.”
Michael Hart in 'The 100, A Ranking of the Most Influential Persons In History,' New York, 1978.
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 secular and religious level. ...It is probable that the relative influence of Muhammad on Islam has been larger than the combined influence of Jesus Christ and St. Paul on Christianity. ...It is this unparalleled combination of secular and religious influence which I feel entitles Muhammad to be considered the most influential single figure in human history.
Dr. William Draper in 'History of Intellectual Development of Europe'
Four years after the death of Justinian, A.D. 569, was born in Mecca, in Arabia, the man who, of all men, has exercised the greatest influence upon the human race... To be the religious head of many empires, to guide the daily life of one-third of the human race, may perhaps justify the title of a Messenger of God.
J.W.H. Stab in 'Islam and its Founder'
Judged by the smallness of the means at his disposal, and the extent and permanence of the work that he accomplished, his name in world's history shines with a more specious lustre than that of the Prophet of Makkah. To the impulse which he gave numberless dynasties have owed their existence, fair cities and stately palaces and temples have arisen, and wide provinces became obedient to the Faith. And beyond all this, his words have governed the belief of generations, been accepted as their rule of life, and their certain guide to the world to come. At a thousand shrines the voices of the faithful invoke blessings on him, whom they esteem the very Prophet of God, the seal of the Apostles.... Judged by the standards to human renown, the glory of what mortal can compare with his?
Washington Irving in 'Life of Muhammad,' New York, 1920.
His military triumphs awakened no pride nor vain glory as they would have done had they been effected by selfish purposes. In the time of his greatest power he maintained the same simplicity of manner and appearance as in the days of his adversity. So far from affecting regal state, he was displeased if, on entering a room, any unusual testimonial of respect was shown to him.
Arthur Glyn Leonard in 'Islam, Her Moral and Spiritual Values'
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.
Charles Stuart Mills in 'History of Mohammadanism'
Deeply read in the volume of nature, though extremely ignorant of letters, his mind could expand into controversy with the wisest of his enemies or contract itself to the apprehension of meanest of his disciples. His simple eloquence was rendered impressive by a manner of mixed dignity and elegance, by the expression of a countenance where the awfulness of his majesty was so well tempered by an amiable sweetness, that it exerted emotions of veneration and love. He was gifted with that authoritative air or genius which alike influences the learned and commands the illiterate.
