Sarojinidevi Naidu's Testimony:"Sense of justice is one of the most wonderful ideals of Islam, because as I read in the Qur'an I find those dynamic principles of life, not mystic but practical ethics for the daily conduct of life suited to the whole world."

Bertrand Russel's Testimony:"Our use of phrase 'The Dark ages' to cover the period from 699 to 1,000 marks our undue concentration on Western Europe..."
"From India to Spain, the brilliant civilization of Islam flourished. What was lost to christendom at this time was not lost to civilization, but quite the contrary..." "To us it seems that West-European civilization is civilization, but this is a narrow view."

Alphonse de LaMartaine's Testimony:" Never has a man undertaken a work so far beyond human power with so feeble means, for he (Muhammad) had in the conception as well as in the execution of such a great design, no other instrument than himself and no other aid except a handful of men living in a corner of the desert. Finally, never has a man accomplished such a huge and lasting revolution in the world, because in less than two centuries after its appearance, Islam, in faith and in arms, reigned over the whole of Arabia, and conquered, in God's name, Persia Khorasan, Transoxania, Western

India, Syria, Egypt, Abyssinia, all the known continent of Northern Africa, numerous islands of the Mediterranean Sea, Spain, and part of Gaul."
"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? The most famous men created arms, laws, and empires only. They founded, if anything at all, no more than material powers which often crumbled away before their eyes. This man moved not only armies, legislations, empires, peoples, dynasties, but millions of men in one-third of the then inhabited world; and more than that, he moved the altars, the gods, the religions, the ideas, the beliefs and the souls."
"On the basis of a Book, every letter which has become law, he created a spiritual nationality which blend together peoples of every tongue and race. He has left the indelible characteristic of this Muslim nationality the hatred of false gods and the passion for the One and Immaterial God. This avenging patriotism against the profanation of Heaven formed the virtue of the followers of Muhammad; the conquest of one-third the earth to the dogma was his miracle; or rather it was not the miracle of man but that of reason.
"The idea of the unity of God, proclaimed amidst the exhaustion of the fabulous theogonies, was in itself such a miracle that upon it's utterance from his lips it destroyed all the ancient temples of idols and set on fire one-third of the world. His life, his meditations, his heroic revelings against the superstitions of his country, and his boldness in defying the furies of idolatry, his firmness in enduring them for fifteen years in Mecca, his acceptance of the role of public scorn and almost of being a victim of his fellow countrymen: all these and finally, his flight his incessant preaching, his wars against odds, his faith in his success and his superhuman security in misfortune, his forbearance in victory, his ambition, which was entirely devoted to one idea and in no manner striving for an empire; his endless prayers, his mystic conversations with God, his death and his triumph after death; all these attest not to an imposture but to a firm conviction which gave him the power to restore a dogma. This dogma was twofold the unity of God and the immateriality of God: the former telling what God is, the latter telling what God is not; the one overthrowing false gods with the sword, the other starting an idea with words.

Michael H. Hart's Testimony:
"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."

Herbert George Wells' Testimony:"The Islamic teachings have left great traditions for equitable and gentle dealings and behavior, and inspire people with nobility and tolerance. These are human teachings of the highest order and at the same time practicable. These teachings brought into existence a society in which hard-heartedness and collective oppression and injustice were the least as compared with all other societies preceding it....Islam is replete with gentleness, courtesy, and fraternity."

Carly Fiorina's Testimony:
"The technology industry would not exist without the contributions of Arab mathematicians"
In one of her lectures, Carly Fiorina, the CEO of Hewlett-Packard, said: " I’ll end by telling a story. There was once a civilization that was the greatest in the world.
It was able to create a continental super-state that stretched from ocean to ocean, and from northern climes to tropics and deserts. Within its dominion lived hundreds of millions of people, of different creeds and ethnic origins.
One of its languages became the universal language of much of the world, the bridge between the peoples of a hundred lands. Its armies were made up of people of many nationalities, and its military protection allowed a degree of peace and prosperity that had never been known. The reach of this civilization’s commerce extended from Latin America to China, and everywhere in between.
And this civilization was driven more than anything, by invention. Its architects designed buildings that defied gravity. Its mathematicians created the algebra and algorithms that would enable the building of computers, and the creation of encryption. Its doctors examined the human body, and found new cures for disease. Its astronomers looked into the heavens, named the stars, and paved the way for space travel and exploration.
Its writers created thousands of stories. Stories of courage, romance and magic. Its poets wrote of love, when others before them were too steeped in fear to think of such things.
When other nations were afraid of ideas, this civilization thrived on them, and kept them alive. When censors threatened to wipe out knowledge from past civilizations, this civilization kept the knowledge alive, and passed it on to others.
While modern Western civilization shares many of these traits, the civilization I’m talking about was the Islamic world from the year 800 to 1600, which included the Ottoman Empire and the courts of Baghdad, Damascus and Cairo, and enlightened rulers like Suleiman the Magnificent.
Although we are often unaware of our indebtedness to this other civilization, its gifts are very much a part of our heritage. The technology industry would not exist without the contributions of Arab mathematicians."
