My Dears,
Before refuting anyone, we should have counter arguments. So if you want to refute him, then bring an evidence with you. And please remain polite and well mannered as the bud-zubani (speaking ill) some times shows bud-emani (ill belief). The point here mentioned is that the Afghanistan is the soil from where the light of Islam would spread around. Now who can deny this. If we look back 10-15 generations(and obviously I am pointing to indo-pak people) ,our ancestors would be shankar, gopal, ramdas and the names like that. So who was responsible for our forefathers accepting Islam. Definitely it were these pious personalilities like Hazrat Ali Hajveri AKA Data Gunj Bakhsh, Khawja Moin-udd-din Chishti Ajmeri and thousands other.
Aur tum par meray Aaqa(Sallalaho Aleyhe Wasallam) ki Inayat na sahi,
Munkiro kalma parhanay ka bhi ehsaan gya.
