Muslims intensely hate Gandhiji. Sardar Patel is even more object of hate to them because he ended Nizam's rule in Hyd and sent Indian troops to Kashmir.
Jinnah rallied UP/Bihar Muslims for Pakistan. But it was funded by Gujarati Muslims.
So, don't be surprized that Islamists hate Gandhiji and Patel.
Why u bother what these folks say. Those who make India strong are obviously hated by anti-nationals.
