Muhammad Ali had been suffering from tuberculosis since the early 1940s. Only his sister and very few other persons close to the family knew this. After the partition of India and creation of Pakistan, he had become the governor general of Pakistan. His work was increased, but his health was deteriorating. To regain his health, he spent many months at his official rest house. The rest house was located at a place named in Ziarat. Jinnah could not regain his health. He died on 11 September 1948 from tuberculosis .
