Here's my two cents
GM Syed is one of the most prominent politicians in the history of sindh and Pakistan. He was integral to the only resolution passed in sindh assembly in 1943 for establishing Pakistan. 1

Later GM Syed remained in Pakistani politics for several years and finally started his separation movement with the name of Jeay Sindh Mahaz. JSM introduced the political ideology of Sindhudesh, a separate country for sindhis. 2

GM Syed was part of Muslim League before Mohammed Ali Jinnah joined the league.
GM Syed made significant literary contributions by writing several books. One of his prominent books is Religion and Reality, translated from sindhi book "Jeeain ditho aahey moon".

I will be quoting some extracts from that book.
