Who once remarked - 'Nehru is a patriot while Jinnah is a politician.'?

The statement 'Nehru is a patriot while Jinnah is a politician' was remarked by the renowned poet and philosopher Sir Muhammad Iqbal. This conversation was notably recalled and documented by Jawaharlal Nehru himself in his book The Discovery of India, describing a visit he made to Iqbal during the latter's final years.
