A bizarre sidelight on Dowie's later years is that he became embroiled in an acrimonious public dispute with a controversial Indian Muslim religious figure, Mirza Ghulam Ahmad, founder of the Ahmadiyya movement. In 1903 they engaged in a widely publicized "prayer duel," each calling upon God to punish the other to expose him as a false prophet. Ahmad and his followers proclaimed Dowie's rapidly ensuing illness, disgrace, and death as a vindication of their religious beliefs. Ahmad died in 1908, a year later than Dowie, although he was several years older than Dowie.
