At the beginning of the third year of the reign, Ulugh Khan and Nusrat Khan, with their amirs and generals, and a large army marched against Gujarat…… - Ziauddin Barani

[As early as in the time of Sultan Iltutmish (1210-1236), soon after the establishment of the Delhi Sultanate in 1206, some Ulama suggested to him to confront the Hindus with a choice between Islam and death. The Wazir Nizamul Mulk Junaidi replied:] “But at the moment in India… the Muslims are so few that they are like salt (in a large dish). If such orders are to be enforced… the Hindus might combine… and the Muslims would be too few in number to suppress(them). However, after a few years when in the capital and in the regions and small towns, the Muslims are well established and the troops are larger, it will be possible to give Hindus, the choice of ‘death’ or ‘Islam’.”

Consequently, it became necessary for the rulers of Islam (the Caliphs) to follow the policy of Iranian Emperors in order to ensure the greatness of True Word, the supremacy of the Muslim religion… overthrow of the enemies of the Faith… and maintenance of their own authority.

'Alpau-d dín was a king who had no acquaintace with learning, and never associated with the learned. When he became king, he came to the conclusion that polity and government are one thing, and the rules and decrees of law are another. Royal commands belong to the king, legal decrees rest upon the Judgment of kázis and mufis. In accordance with this opinion, whatever affair of state came before him, he only looked to the public good, without considering whether his mode of dealing with it was lawful or unlawful. He never asked for legal opinons about poitical matters, and very few learned men visited him. Kázi Mughpisu-d dín, of Bayánah, used to go to court and sit down in private audience with the amirs. Once day, when the efforts were being made for the increase of the tribute and of the fines and imposts, the Sultán told the Kazi that he had several questions to ask him, and desired him to speak the plain truth. The Kazi replied, "The angel of my destiny seems to be close at hand, since your Majesty wishes to question me on matters of religion; if I sepak the truth you will be angry and kill me." The Sulpan said he would not kill him and commanded him to answer his questions truly and candidly. The Kazi then promised to answer in accordance with what he had read in books.... The Sultán smiled at this answer of the Kazi's, and said, "I do not understand any of the statements thou hast made; but this I have discovered, that the khuts and mukaddims ride upon fine horses, wear fine clothes, shoot with Persian bows, make war upon each other, and go out hunting; but of the kharaj (tribute), jizya (poll tax), kari (house tax), and chari (pasture tax), they do not pay one jital. They levy separately the Khut's (landowner's) share from the villages, give parties and drink wine, and many of them pay no revenue at all, either upon demand or without demand. Neither do they show any respect for my officers.
