Jinnah received several threats of murder in June and July 1943 from the Khaksars. The threat to Jinnah's life almost materialized on the afternoon of 26 July 1943. A Khaksar named Rafiq Sabir Maznavi walked up to the Quaid's residence and attacked him with a large knife. Jinnah defended himself by catching hold of the assailant's hand. This softened the blow and Jinnah escaped with no more than a wound on his chin and some cuts on his hand. In the meantime Jinnah's chauffeur and others arrived at the scene and overpowered Sabir. He was subsequently sentenced to five years rigorous imprisonment by a British judge.

In the autumn and winter of 1942-43, Bengal suffered a dreadful famine. The official estimate was that one and a half million died of starvation or by its after-effects. No one knows for sure how many starved to death or died of disease during these months of horror. The shortage of the rice crop would have been overcome by purchases from Burma or Thailand, but these sources were under Japanese control at that time. The provincial government was inefficient and imprudent and allowed the situation to get out of hand, while the central government under Linlithgow did not assert itself effectively. It was not until Wavell took over as Viceroy on 20 October 1943 and took a vigorous interest in the tragedy that anything worthwhile was done to alleviate the suffering.
