Zia-ud-Din Barani is one of the most widely read authors of pre-Mughal India. - Ziauddin Barani

Sons of Mahmud' and kings of Islam! You should with all your royal determination apply yourself to uprooting and disgracing infidels, polytheists, and men of bad dogmas and bad religions, if you wish that you may not have to be ashamed before God and his Prophets and that in your record of life-concerning what you have said and done, the clothes you have worn, and the food you have eatenthey may write good instead of evil. You should consider the enemies of God and His Faith to be your enemies and you should risk your power and authority in overthrowing them, so that you may win the approval of God and the Prophet Mohammad and of all prophets and saints. You should not content yourself merely with levying the poll-tax and the tribute from the infidels and you should not allow infidelity to be preserved in spite of your royal power and authority. You should strive day and night for the degradation of infidelity so that (on the Day of Judgment) you may be raised (from your graves) among the prophets and be blessed with the sight of God for all eternity and "may find a seat among the truthful near the Powerful King of (God)."

Ziyauddin Barani voiced his opinion against the Hanafi school when he wrote as follows in his Fatwa-i-Jahandari: “If Mahmud… had gone to India once more, he would have brought under his sword all the Brahmans of Hind who, in that vast land, are the cause of the continuance of the laws of infidelity and of the strength of idolators; he would have cut off the heads of two or three hundred thousand Hindu chiefs. He would not have returned his Hindu-slaughtering sword to its scabbard until the whole of Hind had accepted Islam. For Mahmud was a Shafiite, and according to Imam Shafii the decree for Hindus is Islam or death, that is to say, they should either be put to death or accept Islam. It is not lawful to accept jiziya from Hindus who have neither a prophet nor a revealed book.”

There is no denying the fact that Ziyauddin had his prejudices, his weaknesses and his handicaps.... But after all these decuctions have been made, the Tarikh-i-Firoz Shahi remains the greatest book that has survived to us from the Sultanate period. Its eminence in this respect is unchallengable; and so long as the history of India is studied, Barani cannot be ignored...
