"Shykh Nuruddin Mubarak Ghaznavi was the most important disciple of Shykh Shihabuddin Suhrawardi, founder of the second most important sufi silsila after the Chishtiyya, who died in Baghdad in 1235 AD. Ghaznavi had come and settled down in India where he passed away in 1234-35 AD. He served as Shykh-ul-Islam in the reign of Shamsuddin Iltutmish , and propounded the doctrine of Din Panahi. Barani quotes the first principle of this doctrine as follows in his Tarikh-i-Firuzshahi. “The kings should protect the religion of Islam with sincere faith… And kings will not be able to perform the duty of protecting the Faith unless, for the sake of God and the Prophet’s creed, they overthrow and uproot kufr and kafiri , shirk and the worship of idols. But if the total uprooting of idolatry is not possible owing to the firm roots of kufr and the large number of kafirs and mushriks , the kings should at least strive to insult, disgrace, dishonour and defame the mushrik and idol-worshipping Hindus, who are the worst enemies of God and the Prophet. The symptom of the kings being the protectors of religion is this:- When they see a Hindu, their eyes grow red and they wish to bury him alive; they also desire to completely uproot the Brahmans, who are the leaders of kufr and shirk and owning to whom kufr and shirk are spread and the commandments of kufr are enforced… Owing to the fear and terror of the kings of Islam, not a single enemy of God and the Prophet can drink water that is sweet or stretch his legs on his bed and go to sleep in peace."

““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.”
