“It is a great shame for anyone to listen to the accusation that Islam is a lie and that Muhammad was a fabricator and a deceiver. We saw that he remained steadfast upon his principles, with firm determination; kind and generous, compassionate, pious, virtuous, with real manhood, hardworking and sincere. Besides all these qualities, he was lenient with others, tolerant, kind, cheerful and praiseworthy and perhaps he would joke and tease his companions. He was just, truthful, smart, pure, magnanimous and present-minded; his face was radiant as if he had lights within him to illuminate the darkest of nights; he was a great man by nature who was not educated in a school nor nurtured by a teacher as he was not in need of any of this.”

― Thomas Carlyle, On Heroes, Hero Worship and the Heroic in History

“I believe 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 much needed peace and happiness.
I have studied him – the man and in my opinion is far from being an anti–Christ. He must be called the Savior of Humanity.
I have prophesied about the faith of Mohammad that it would be acceptable the Europe of tomorrow as it is beginning to be acceptable to the Europe of today.”

― George Bernard Shaw

“I am not a Muslim in the usual sense, though I hope I am a “Muslim” as “one surrendered to God,” but I believe that embedded in the Quran and other expressions of the Islamic vision are vast stores of divine truth from which I and other occidentals have still much to learn, and ‘Islam is certainly a strong contender for the supplying of the basic framework of the one religion of the future.'” W. Montgomery Watt, ISLAM AND CHRISTIANITY TODAY, London, 1983, p. ix.

“But Islam has a still further service to render to the cause of humanity. It stands after all nearer to the real East than Europe does, and it possesses a magnificent tradition of inter-racial understanding and cooperation. No other society has such a record of success uniting in an equality of status, of opportunity, and of endeavors so many and so various races of mankind . . . Islam has still the power to reconcile apparently irreconcilable elements of race and tradition. If ever the opposition of the great societies of East and West is to be replaced by cooperation, the mediation of Islam is an indispensable condition. In its hands lies very largely the solution of the problem with which Europe is faced in its relation with East. If they unite, the hope of a peaceful issue is immeasurably enhanced. But if Europe, by rejecting the cooperation of Islam, throws it into the arms of its rivals, the issue can only be disastrous for both.” H.A.R. Gibb, WHITHER ISLAM, London, 1932, p. 379

“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 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.” G.B. Shaw, THE GENUINE ISLAM, Vol. 1, No. 81936

Gandi on Islam:

To those who have been indulging in a campaign of abuse and vilification I would say, ‘Islam enjoins you not to revile even an enemy. The Prophet treated even enemies with kindness and tried to win them over by his fairness and generosity
The ‘Quit India’ Resolution, My Non-violence

In my view, Islam did not attain its greatness by the power of the sword but entirely through the self- immolation of its fakirs. It is soldier-like to allow oneself to be cut down by a sword, not to use the sword on another.
To Shankarlal on ideas about Satyagraha, Selected Letters of Mahatma Gandhi

Mahatma Gandhi famously said about Mohammad:

I wanted to know the best of life of the one who holds today the undisputed sway over the hearts of millions of mankind. I became more than convinced that… it was the rigid simplicity, the utter self-effacement of the Prophet… his intense devotion to his friends and followers, his intrepidity, his fearlessness, his absolute trust in God and his own mission.
