“The chroniclers of the early Turkish rulers of India take pride in affirming that Qutbuddin Aibak was a killer of lakhs of infidels. Leave aside enthusiastic killers like Alauddin Khalji and Muhammad bin Tughlaq, even the "kind-hearted" Firoz Tughlaq killed more than a lakh Bengalis when he invaded their country. Timur Lang or Tamerlane says he killed a hundred thousand infidel prisoners of war in Delhi. He built victory pillars from severed heads at many places. These were acts of sultans. The nobles were not lagging behind. One Shaikh Daud Kambu is said to have killed 20,000 with his dagger. The Bahmani sultans of Gulbarga and Bidar considered it meritorious to kill a hundred thousand Hindu men, women and children every year….. The rite of Jauhar killed the women, the tradition of not deserting the field of battle made Rajputs and others die fighting in large numbers. When Malwa was attacked (1305), its Raja is said to have possessed 40,000 horse and 100,000 foot.43 After the battle, "so far as human eye could see, the ground was muddy with blood"…. Under Muhammad Tughlaq, wars and rebellions knew no end. His expeditions to Bengal, Sindh and the Deccan, as well as ruthless suppression of twenty-two rebellions, meant only depopulation in the thirteenth and first half of the fourteenth century. For one thing, in spite of constant efforts no addition of territory could be made by Turkish rulers from 1210 to 1296; for another the Turkish rulers were more ruthless in war and less merciful in peace. Hence the extirpating massacres of Balban, and the repeated attacks by others on regions already devastated but not completely subdued….. Mulla Daud of Bidar vividly describes the war between Muhammad Shah Bahmani and the Vijayanagar King in 1366 in which "Farishtah computes the victims on the Hindu side alone as numbering no less than half a million." Muhammad also devastated the Karnatak region with vengeance….. Under Akbar and Jahangir "five or six hundred thousand human beings were killed," says emperor Jahangir. The figures given by these killers and their chroniclers may be a few thousand less or a few thousand more, but what bred this ambition of cutting down human beings without compunction was the Muslim theory, practice and spirit of Jihad, as spelled out in Muslim scriptures and rules of administration.”
