Anyways wiki will give you a nice base line from which to start:
Persecution of Hindus - Wikipedia, the free encyclopedia
Could not testify against Muslims, could be killed by Muslims outright with only a tribute of blood money to be payed, could not in fact practice their religion in public or prosteltyze to Muslims in any way and suffered immense state and non-state sponsored persecution and numerous pogroms.Dhimmi's could own property and could, largely, practice their religion freely.
Fellows of the book were allowed to practice, this was not the case for the Pagans and it depends when exactly we're talking about in Christian Europe, eg when the Christian religion was first adopted by the Roman empire they were very tolerant of other religions in the territories under their control and that would include the peoples who still practiced Paganism.Was it perfect, of course not.
I'd also like to see links with further information on this.
In comparison to Christian Europe, they were free to practice.
