In this book the Promised Messiah (as), discusses the philosophy of divine revelation, the three categories of people who claim to receive revelation, and the distinction of the truthful from the false. He then establishes his truthfulness by documenting over 200 Signs, including the fulfilment of prophecies made by the Holy Prophet Muhammad, may peace and blessings of Allah be upon him, other men of God, earlier scriptures, and his own revelations spanning over twenty-five years.
