I would like to know more about Jinnah's contribution from you.
Being an Indian, ...I know of his contributions to the so called "freedom struggle" against the indians.
With this attitude, and so much disrespect for a true-blue Indian leader, you won't learn anything my friend. You are destined to be stuck with the lollypops doled out by Indian high school's "official" text books.
Sorry!
For the others, there are many books that you ought to read. In fact why not go to the source and check out the actual letters, memos, and directives by the players of that era. Why to let a historian tell "his-story".
A lot of such memos, letters, and directives are part of the "Transfer of Power".
Make sure you don't let your own biases distort your reading. If Transfer of power is too much, then a concise reading is "Jinnah the sole spokesman" by Jalal. This book so far has the least amount of bias. Even better than the gora writers.
Happy reading!
