Dear brother there is long history of distorsion of facts in India. Go to some independent and authentic history books.No muslim ruler is allowed to use any force on non muslims under his rule if he is a true muslim. Regarding Mohammad bin qasim(RA) the Hindues of sindh made his idol and began to worship him because of his humility and just character.It was he who saved the masses form the unjust Huindu rulers.All the sindhi hindues joined his army at will and wanted to expand his rule.Unfortunately he was called back. Brother Be just and open minded.
