 In December 1912 , Jinnah addressed the annual meeting of the Muslim League , although he was not yet a member . He joined the following year , although he remained a member of the Congress as well and stressed that League membership took second priority to the " greater national cause " of a free India . In April 1913 , he again went to Britain , with Gokhale , to meet with officials on behalf of the Congress . Gokhale , a Hindu , later stated that Jinnah " has true stuff in him , and that freedom from all sectarian prejudice which will make him the best ambassador of Hindu – Muslim Unity " . Jinnah led another delegation of the Congress to London in 1914 , but due to the start of the First World War found officials little interested in Indian reforms . By coincidence , he was in Britain at the same time as a man who would become a great political rival of his , Mohandas Gandhi , a Hindu lawyer who had become well known for advocating satyagraha , non @-@ violent non @-@ cooperation , while in South Africa . Jinnah attended a reception for Gandhi , and returned home to India in January 1915 .
