This small booklet is a chapter taken from AHMADIYYAT: The Renaissance of Islam by Muhammad Zafrulla Khan, a distinguished scholar of Islam. It briefly narrates an extremely significant encounter between Hazrat Mirza Ghulam Ahmad of Qadian, the Promised Messiah and Mahdi, peace be on him, and Dr. John Alexander Dowie, the founder of Zion City, a bitter enemy of Islam who had claimed to be Elijah III, the precursor of Jesus Christ. Dr. Dowie was intolerant of Islam and abusive of Muhammad, the Holy Prophet of Islam, peace and blessings of God be on him. He had announced that he would finish Islam and would establish his brand of Christianity–Christian Catholic Church–all over the world. Hazrat Mirza Ghulam Ahmad, peace be on him, challenged Dr. Dowie for a “prayer duel”, and prophesied that Dr. Dowie will meet a tormented death in the life of the Promised Messiah.

This booklet deals with the fulfillment of that grand prophecy which was a sign of God for America and the West, proving the truthfulness of Hazrat Mirza Ghulam Ahmad, the Promised Messiah and Mahdi, peace be on him.
