Buddhist idols were found even in Afganistan. Many places in Pakistan have hindu sites of historic relavance. If Pakistan claims to represent the fact that they are custodians, then they should agree to the fact that their ancestors were Hindus and were invaded by Mugals or Arabs like Muhammad bin Qasim, Mahmud of Ghazni, Mohammed Ghori and Alexander, Genghis Khan they crossed the Hindukush into India. India was never invaded from the Himalayan route.
After Timur's empire disintegrated, his descendant Babur, having inherited a small kindgom in Ferghana (present day Uzbekistan) and losing it, ended up as king of Kabul. With dreams of emulating Timur, and cannons which were gifted to him by the Ottomans, he invaded India, won at Panipat in 1526 and established the Mughal empire in Delhi. The word Mughal was what the Persian Shah referred to him as. It was used as a derogatory term. But it meant Mongol, and Babur decided to adopt that as the name for his dynasty. Babur was a Timurid (direct descendant of Timur), and his maternal grandmother was a direct descendant of Genghis Khan. Babur was much inspired by both Timur and Genghis.
Since more of the Attacks were via Hindukush presently Afganistan and parts of Pakistan, All the local population was either killed or were forced converts. As per history, Sindh was the wild frontier region of al-Hind, inhabited mostly by semi-nomadic tribes. Raja Dahir(A Hindu) was the ruler. The army of Muhammad bin Qasim probably numbered 20,000 - 25000 men, while the Army of Sindh had 60 elephants and 20000 to 50000 soldiers. In the ensuing battle in June 712 AD, the Hindu army fled the field after Raja Dahir was killed, 15,000 going to Rawar and others to Brahmanabad. Arabs marched north after the siege and capture of Rawer. Brahmanabad, then Alor (Aror) and finally Multan led by by Muhammad bin Qasim.
After battles all fighting men were executed and their wives and children enslaved in considerable numbers and the usual fifth of the booty and slaves were sent to Hajjaj
After the capture of Multan, Muhammad assembled an army of 50,000 soldiers,the essentially Arab army that had captured Sindh had been joined by Muslim volunteers, new converts then spearheading the Arab conquests across the Oxus and Muhammad b. Qasim, now master of Sindh and Southern Punjab. This may explain the expedition of Muhammad up to the foothills of Kashmir along the Jhelum in 713 AD, the attack on Al-Kiraj (probably the Kangra valley) and sending 10,000 cavalry to defeat the Army of Hara Chandra, King of Qinnauj (probably not Kanauj) near Udaypur on the banks of Ghaggar, 14 miles south of Alwana. Chandrapida, Karakota dynasty King of Kashmir.
So the people in Pakistan who call themselves muslims were no other than Hindus who got converted because of fear of slaughtering after conquest by Arab invaders or sons from Hindu mothers who were enslaved by Arabs.
