Mushtaque Ahmad Wajdi was a senior officer at the time of formation of Pakistan. Late he retired as the auditor general of Pakistan. On page 148 of his book "Hungamon mein zindagi' (A tumultuous Life) he writes:
"On May 30 1947, Shujaat Ali Husni invited all the Muslim officers over tea in Delhi with an emphasis on attendance. The reason was not known. On reaching there we saw Qaid-e-Azam, Liagat Ali Khan, Sardar Abdur Rab Nashtar and some others. As the tea was over, it was announced that Qaid-e-Azam will speak.
After the speech while replying to a question Qaid-e-Azam said, "From now on, the nationality of Indian Muslims will be Indian. They will have nothing to do with Pakistan."
I was shocked to hear this. Five crore Muslims were declared Indians at one go. Until yesterday they were promised a new country which would be an abode of peace for them. They were asked for sacrifices on this ground and they sacrificed their lives and fortune for this cause. Today they were pushed into a virtual hell with two words. What happened to the Two nation Theory?
Then I thought that after all Qaid-e-Azam, Liaqat Ali Khan and other leaders were also Indians. Definitely, they will stay back and take care of them, but that was not to happen."
In his book, Pathway to Pakistan, Choudhry Khaliquzzaman writes,
"Qaid-e-Azam had now realised the dangers facing Muslims left behind in India. On August 1, 1947, before leaving for Karachi, Mr Jinnah invited all the Muslim members of the Legislative Assembly to bid farewell. Mr Rizwanullah asked some unsavoury questions about the status and future of the Muslims left in India. Never before had I seen Mr Jinnah so nervous and at a loss for words because he could clearly foresee how the Muslims were going to suffer. As the situation became really unpleasant I requested my colleagues to stop the discussion. I believe that this last conversation compelled Mr Jinnah to say good bye to the Two Nation Theory on August 11, 1947 as the designated Governor General and the President of the Legislative Assembly."
