You were claiming that Pakhtunkhwa was part of Punjab province of Mughal empire. I told you that no subah by name of Punjab existed during Mughal period and the lands beyond Indus were part of their Kabul province. Under Durranis, Kabul was a "wilayat" while Peshawar had "hukomat-i-Ala" status. Lahore was also had a wilayat status under Durranis while Multan had "hukomat-i-Ala" status.
Sikh empire had four provinces, Lahore, Kashmir, Multan and Peshawar.
British India had very large provinces and Punjab province under them was whole lot bigger than "Lahore" province of Mughals, Durranis and Sikhs. "Punjab" province never existed before British, same is case with NWFP.
