Not really! "Pakistan Scheme" was the idea of Ch. Rahmat Ali which was opposed by signficant majority of Muslim leaguers including Jinnah, Zafarullah and Iqbal. Iqbal's vision of one or more Muslim states/countries was much different than Ch. Rahmat Ali's ideas. Go check why Ch. Rahmat Ali was not allowed into Punjab when the Lahore Resolution was presented in March 1940? Why was he forced out of Pakistan in 1948 and why was his remains not allowed back into Pakistan after his death? Anyways, Iqbal's letter to Ed. Thompson was in 1934, before the Indian Constitution of 1935 was adopted in India. ML and Iqbal never accepted it as a whole specially its concept around federation and center. Iqbal purused Jinnah to work for achieving free Muslim State(s). He even suggested that if this is not politically possible, then there would be civil war and bloodshed in India for the same objective. Iqbal believed that under Congress, empowered by 1935 constitution, NW India (Muslim majority provinces) could well become another Palestine. I attach excerpts from one of Iqbal's letter to Jinnah written in 1937 as evidence of what I wrote above.
