Sultan Firoz Tughlaq writes in his Fatuhat that he appeased by means of gifts the heirs of those who had been deprived of a limb, nose, eye, hand or … - Firuz Shah Tughlaq

I encouraged my infidel subjects to embrace the religion of the prophet, and I proclaimed that every one who repeated the creed and became a Musalman should be exempt from the jizya or poll-tax. Information of this came to the ears of the people at large, and great numbers of Hindus presented themselves, and were admitted to the honour of Islam. Thus they came forward day by day from every quarter, and, adopting the faith, were exonerated from the jizya, and were favoured with presents and honours.

Some Hindus had erected a new idol-temple in the village of Kohana, and the idolaters used to assemble there and perform their idolatrous rites. These people were seized and brought before me. I ordered that the perverse conduct of the leaders of this wickedness should be publicly proclaimed, and that they should be put to death before the gate of the palace. I also ordered that the infidel books, the idols, and the vessels used in their worship, which had been taken with them, should all be publicly burnt. The others were restrained by threats and punishments, as a warning to all men, that no zimmi could follow such wicked practices in a Musulman country.

Sultan Firuz Tughlaq (1351-88 A.D.) declared that all those who turned Musalman would be exempted from paying Jizya. He says in FutuhÁt-i-Firuz Shahi, ‚I (Rultan Tiruz Rhah Tughlaq) encouraged my infidel subjects to embrace the religion of the Prophet, and I proclaimed that everyone who repeated the creed and became a Musalman should be exempt from the Jizya, or poll-tax. Information of this came to the ears of the people at large and great number of Hindus presented themselves and were admitted to the honour of Islam. Thus they came forward day by day from every quarter, and adopting the faith, were exonerated from the Jizya, and were favoured with presents and honours‛.
