I have read that,

"There is ample edidence in the pages of BARANI and IBN BATUTA to show that he was not fond of shedding blood for its own sakeand that he could be kind, generous and just even towards his enemies"(A SHORT HISTORY OF MUSLIM RULE IN INDIA BY ISHWAR PRASAD)

But contrary to that you have mentioned that,
"The contemporary historians like Ibn Batuta and Barani blame him for all the unfortunate events" ???????
