My dear friend and colleague Narain Kataria has an excellent piece on the jihad against the Hindus:
The conquest of India by Islamic invaders is a long and dreadful narrative of multiple ferocious wars between the invaders and the valiant Hindu Rajas who ruled over different parts of India during medieval times. The barbaric invaders, including Muhammad Ghauri and Babur, took morbid delight in building towers of the skulls of slaughtered 'kaffirs' (read Hindus), a stark fact, proudly recorded by a number of Muslim historians in great detail. Most braveheart Hindu rulers zealously defended their motherland, their subjects and above all their honor at a terrible cost; unlike the Arab conquest of the Persian empire within a short span of two decades and similar fate of Byzantine empire and smaller kingdoms of central Asia. In sharp contrast, the Islamic invaders had to fight multiple tortuous, gut-wrenching battles for centuries to subjugate the Hindus. The resistance offered by the masses to invaders and freebooters was formidable indeed. Occasionally there were some traitors, too, like Raja Jaichand of Kannauj, whose name has become synonymous with treachery.
The hostility between two kingdoms, namely the Chauhans of Rajasthan and Gahadwala Rajputs of Kannauj was a major cause of the defeat of Prithviraj Chauhan in 1192. Had the armies of two gutsy Hindu rulers stood united in the battle of Tarain, the invading armies could have been defeated.
The atrocities committed by Muslim rulers on Sikhs of Punjab and Marathas in south were horrendous. Jahangir had murdered the fifth Sikh Guru Arjan Dev in a most diabolical manner. The epitome of courage Arjan Dev was made to sit on a hot plate and hot sand was poured on him to torture him to death. Later on Aurangzeb, the cruelest of all Muslim kings not only beheaded Guru Tegh Bahadur, but also murdered four gallant sons of Guru Gobind Singh. Two elder sons, Sahibzade Ajit Singh and Junjhar Singh attained martyrdom in 1704 during the battle of Chamkaur Sahib, while the younger sons Fateh Singh and Zorawar Singh were bricked alive in 1705 at Sirhind by Faujdar Wazir Khan, under orders of Aurangzeb.
Starting with the invasion of Sind by Muhammad bin Qasim in 712 A.D. the next 900 years witnessed a relentless onslaught by hordes of Muslim invaders pouring in through Khyber and Bolan passes. Among the barbaric murderers and freebooters were Mahmud Ghazanvi, Muhammad Ghauri, Babur, Ahmad Shah Abdali and Nadir Shah. In fact, Guru Nanak has given in the Babur Vani a vivid description of the atrocities committed by invaders on the hapless Hindus of Punjab and north-western India. According to the eminent historian, Will Durant, "the Mohammedan conquest of India is perhaps the bloodiest story of history". He calls it a discouraging tale, for its only lesson was that civilization is a precarious thing, whose delicate complex of order and liberty, culture and peace could be overthrown at any time by barbarians invading from without and multiplying within." [Source: Will Durant, The Story of Civilization, Part I, p. 459].
A detailed narrative of the tyranny and atrocities committed by Muslim invaders was given by a well known Muslim author and thinker, Rizwan Salim, who wrote in The Hindustan Times, New Delhi, on December 28, 1997, an article titled, "What the invaders really did?" justifying the demolition of Babri Masjid in 1992. Rizwan Salim highlighted that the wrecking of Hindu temples went on from the early years of the eighth century to well past 1700 A.D. a period of almost 1000 years. [Source : The Hindustan Times, New Delhi, December 28, 1997]. Every Muslim ruler of Delhi (or Governor of the Province) spent most of his time fighting the Hindu kings in the north and the south, the east and west. Rizwan continues emphasizing that "savages at a very low level of civilization and no culture worth the name began entering India from the early eighth century onwards. Islamic invaders demolished Hindu temples, destroyed unaccountable sculptures and idols, plundered innumerable palaces and forts of the Hindu kings, killed vast number of Hindu men and carried off Hindu women. This story, the educated - and lot of even the illiterate Indians - know very well. The history books recount it in a remarkable detail. [Source: Ibid].There's so much more. Read the whole thing here.
