Please elaborate on Ghazwa-e-hind and comment on the ahadith that are often quoted in this regard.
I have tried to find out the sources of the traditions. None of them is found in reliable sources like Bukhari, Muslim, Mu'atta etc. If we suppose them to be reliable they talk about an even that has happened already. They do not talk about Pakistanis fighting Indians. They talk about Arabs on an expedition to India and conquering it.
