"Ziauddin Barani who was an Indian jurist, historian, political thinker, writer, and a companion of Sultan Muhammad b. Tughluq , wrote a Fürstenspiegel, a Mirror of Princes, akin to Machiavelli’s The Prince, the Fatāwā-yi Djahāndārī, in order to educate the de facto rulers of the day, the sultans, in their duty towards Islam in an age of corruption. Barani advises sultans to enforce the sharī‘a, to curb unorthodoxy , to degrade the infidel, who must be treated harshly. The Sultans must fight like the Prophet until all people affirm that “there is no God but Allah.” It is the duty of Muslim rulers to overthrow infidelity, uproot it completely, and apply the Holy Law, the Sharia on all."

““high offices and are successful in their work… they will make people of their own kind their helpers, supporters, colleagues. They will not allow nobles and free-born men and men of merits to come anywhere near the affairs of the government.”

““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… All Gujarat became a prey to the invaders, and the idol, which after the victory of Sultan Mahmud and his destruction of of Manat, the Brahmans had set up under the name of Somanat, for the worship of the Hindus, was carried to Delhi where it was laid for the people to tread upon…”

“Even after his conversion to Islam, the Hindu remained an object of abhorrence... Barani is so maliciously vituperative against Hindus that even many modem Muslim scholars feel embarrassed at his language and find it difficult to defend him. It must, however, be remembered that Barani belonged to the common run of Muslim theologians and chroniclers. He was a personal friend of men like Amir Khusrau and Ala Hasan Sijzi and was a disciple of no less a Sufi than Shaikh Nizamuddin Auliya. He possessed charming manners and was known for his wit and humour. But in the case of Hindus, his wit turned into rage. He is copiously quoted by future chroniclers like Nizamuddin Ahmad, Badaoni and Farishtah, who all praise him highly. Most of medieval Muslim chroniclers wrote in the idiom of Barani; only he excelled them all. All medieval chroniclers were scholars of Islamic scriptures and law. They often quote from these to defend or justify the actions of their kings in relation to their non-Muslim subjects.”

““……Malik Naib Kafur marched on to Ma’bar, which he also took. He destroyed the golden idol temple of Ma’bar, and the golden idols which for ages had been worshipped by the Hindus of that country. The fragments of the golden temple, and of the broken idols of gold and gilt became the rich spoil of the army…”

“The Indian Muslim nobles, who were local converts, also rose to be officers in the upper cadres, but foreigners were always preferred. The fourteenth century Persian chronicler Ziyauddin Barani, who was born in India but traced his ancestry to a Turki Noble, credits the foreigner Turks with all possible virtues and the Indian Muslims with all kinds of imperfections. The invectives he hurls on the converted Sultan Nasiruddin Khusrau Shah , are too well known to need repetition.”

“The majority of religious scholars and wise men of early as well as later time have been sure that if Muslim kings strive with all their might and power and the power of all their supporters on this path, the following objects will be attained:-the true Faith will gain a proper ascendancy over the false creeds; the True Word will be honoured; the traditions of infidelity and polytheism will be weakened; Musalmans will be favoured and honoured; infidels and men of bad faith will be faced with destitution and disgrace; the orders of the unlawful state and the opposed creeds will be erased; the laws of the shari'at will be enforced on the seventy-two communities; and the enemies of God and the Prophet will be condemned, banished, repudiated and terrorised.”
