Dr. Pattabhi Sitaramayya, Presidential Address to the Fifty-fifth Session of the Indian Congress, Jaipur, 1948.
“(The Muslims had) enriched our culture, strengthened our administration, and brought near distant parts of the country… It (the Muslim Period) touched deeply the social life and the literature of the land.”

N.S. Mehta, in ‘Islam and the Indian Civilization,’ reproduced in ‘Hindustan ke Ahd-i-Wusta ki ek Jhalak,’ by S.A. Rahman.
“Islam had brought to India a luminous torch which rescued humanity from darkness at a time when old civilizations were on the decline and lofty moral ideals had got reduced to empty intellectual concepts. As in other lands, so in India too, the conquests of Islam were more widespread in the world of thought than in the world of politics. Today, also, the Islamic World is a spiritual brotherhood which is held together by community of faith in the Oneness of God and human equality. Unfortunately, the history of Islam in this country remained tied up for centuries with that of government with the result that a veil was cast over its true spirit, and its fruits and blessings were hidden from the popular eye.”

Brooks Adams in ‘The Law of Civilization and Decay,’ London, 1898, pp. 313-17.
“Very soon after Plassey the Bengal plunder began to arrive in London, and the effect appears to have been instantaneous, for all authorities agree that the Industrial Revolution, the event that has divided the l9th century from all antecedent time, began with the year 1760….Plassey was fought in 1757, and probably nothing has ever equaled the rapidity of the change which followed….In themselves inventions are passive, many of the most important having laid dormant for centuries, waiting for a sufficient store of force to have accumulated to have set them working. That store must always take the shape of money, and money not hoarded, but in motion.

“…Before the influx of the Indian treasure, and the expansion of credit which followed, no force sufficient for this purpose existed….The factory system was the child of ‘Industrial Revolution,’ and until capital had accumulated in masses, capable of giving solidity to large bodies of labour, manufactures were carried on by scattered individuals….Possibly since the world began, no investment has ever yielded the profit reaped from the Indian plunder, because for nearly fifty years Great Britain stood without a competitor.”

Zaheeruddin Babar in his Autobiography ‘Tuzuk-i-Babari,’ (Founder of Mughal Dynasty, Ruled India 1526-1530).
“There are neither good horses in India, nor good meat, nor grapes, nor melons, nor ice, nor cold water, nor baths, nor candle, nor candlestick, nor torch. In the place of the candle, they use the divat. It rests on three legs: a small iron piece resembling the snout of a lamp… Even in case of Rajas and Maharajas, the attendants stand holding the clumsy divat in their hands when they are in need of a light in the night.
“There is no arrangement for running water in gardens and buildings. The buildings lack beauty, symmetry, ventilation and neatness. Commonly, the people walk barefooted with a narrow slip tied round the loins. Women wear a dress …”

Humayun Kabir in ‘The Indian Heritage,’ 1955, p. 153.
“Islam’s democratic challenge has perhaps never been equaled by any other religious or social system. Its advent on the Indian scene was marked by a profound stirring of consciousness. It modified the basis of Hindu social structure throughout northern India.”
