Mahmood is reported to be fascinated "with the role sunspots played in triggering the French and Russian Revolutions, World War II and assorted anti-colonial uprisings." According to his book ""Cosmology and Human Destiny"", Mahmood argued that sunspots have influenced major human events, including the French Revolution, the Russian Revolution, and World War II. He concluded that governments across the world ""are already being subjected to great emotional aggression under the catalytic effect of the abnormally high sunspot activity under which they are most likely to adapt aggression as the natural solution for their problems"". In this book, first published in 1998, he predicted that the period from 2007 to 2014 would be of great turmoil and destruction in the world. Other books written by him include a biography of the Islamic prophet Muhammad titled ""First and the Last"", while his other books are focused more on the relation between Islam and science like "Miraculous Quran", "Life After Death and Doomsday", and "Kitab-e-Zindagi" (in Urdu).
