Sindh? (Arabic script: ????) is spoken by about 25 million people(in 2011) in the province of Sindh. However only 5% people are Sindhi-speaking in the largest city of Karachi, Pakistan. It is an Indo-European language, related to Balochi, Kutchi, Gujarati, Rajasthani language and other Indo-European languages prevalent in the region with substantial Persian, Turkish and Arabic loan words. In Pakistan it is written in a modified Arabic script, in fact most Sindhi's are mostly Muslim(but only in Pakistan),the Hindu sindhis who migrated to India after partition(currently are about 6 million) still register their mother tongue as sindhi along with some other 3 million Hindu Sindhis living in Pakistan,that's why it is largely believed that there is substantial number of Hindu Sindhis.
