He was born in herat and why are you avoiding a simple question dude? If its a difficult topic for you don't reply. There is no need to cry.
Debatable whether multan or herat. But anyway, let's disregard that for now - for argument's sake let's assume he's born in Herat .
He allied with numerous balochi and pashtun tribes when jihad against the Maratha empire was declared, also siding with local Muslims (Afghan expats near Delhi) in India proper.
The third battle of panipat, so glorified in recent Bollywood history, was a straightforward unification of Afghan, Pakistani and Indian Muslims and even Indian dharmics (Jats, Rajputs) against the Maratha invaders from the Deccan.
As an aside - the third battle of panipat has been entirely presented fraudulently by Maratha fanboys. Bollywood would have us believe it was some heroic Hindu "liberation" of Delhi, when the harsh truth was that Maratha deccan raiders were no different and no less "foreign" to Delhi than Abdali's Afghanis. Delhi was a Mughal fiefdom equidistant from Maratha and afghani heartlands. Both marathas and Afghanis simply wanted to vassalise the Mughal remnants and Delhi was no different. To portray Maratha designs on Delhi as some "Hindu liberation" is utter desperation to rewrite subcontinental history and ignore the reality that the mughals owned it AND the marathas were foreigners from the Deccan. Anyway, I digress.
Notable commanders who served under Ahmad Shah Abdali specifically and were from coterminous Pakistan: Mir Muhammad Nasir Khan I, Zabardast Khan Tanoli (who was his principal army chief).
As for his prior campaigns in Pakistani lands, he mainly fought against established mughal fiefdoms there. Once he defeated them, he extracted wealth and military men from their ranks to use in later expeditions against the marathas. Hindus were nowhere to be seen in this particular theatre.
