Well Maulana Abul Kalam Azad was born in Mecca to a Meccan mother and a Bengali father. His father's family had migrated to Bengal over 400 years ago from Herat in Afghanistan. Still he considered himself and Indian nationalist. He had first generation Meccan blood from his mother's side and was born in Mecca but still called India his home.
Jinnah on the other hand belonged to a Hindu Rajput family and only his grand father-Poonja Gokuldas Meghji- had converted to Islam as a Khoja shia and became a founder of Pakistan and a proponent of Two nation theory.
India is not defined by a particular ethinicity, language or even a single religion. It has thousands of years of migrations of various people and cultures that settled in India and called it home and were part of the evolution of the Indian culture. Similarly, Indian influence spread to Indonesia, Thailand, and even Central Asia were most of these countries have stan (including Pakistan). Sthan is afterall a Sanskrit derived word meaning Place. Similarly, scientific knowledge passed on from India to Baghdad led to the golden age under the Abassids. While in the East, Buddhism and spread of the Cholan empire at different times of history influenced the culture and evolution of societies there.
I think we're talking about Hindi-Urdu here, not India and Pakistan, or Jinnah & Kalam. Please stop diverting the topic being discussed.
