Let get one thing stright when
Mohammad Bin Qasim , landed in shore of Lands
1- There was no political statement that he must create Pakistan so he landed
2- There was no mandate to issue Pakistani passport
3- People of his domain were not called Pakistani , but perhaps citizens of Ummayd Dynasty
So the man came , won the battles bravely and deserves credit around Year 700's
But in end , No Pakistan was created by him or his King
Fast forward 1857, after many Kings and Governors passed , a new Political movement commenced which was based around establishing an educated mandate to grow awareness in people to focus on education and not be a
nominal member of society. And this is attributed to Sir Syed and later a political party was created
All Muslims League , the party itself seized to exist after Independence.
It is important to know that
"All India Muslim League" is not Nawaz Sharif's party he created a similar sounding party
So in end , the political movement that commenced from 1857 ~ 1947 resulted in formation of Pakistan
While some credit may be due for Mohammad Bin Qasim , but when when we talk about History , Pakistan must teach the kids full scope of our history
Clearly every one is visibly educated and not holding sword or riding horse
It is correct to say , at a Religious level our religion is same as Mohammad Bin Qasim but
really our identity is connected to Islam and the hard work of educated people who politically were smart to deand a independence at right time.
