Sarojini Naidu, a prominent poet and freedom fighter, used this phrase to describe Jinnah in her 1918 biography titled "Muhammad Ali Jinnah: An Ambassador of Unity". This was during a period when Jinnah was actively involved in both the Indian National Congress and the Muslim League and played a key role in negotiating the Lucknow Pact of 1916, which saw the two major political parties agree on a scheme of constitutional reforms.
