Round Four: The Spell Remains (1974-2016)

As Muhammad Ali's devotion to Islam grew, he began to pray five times each day, discussed religion with friends, and frequently traveled the Muslim world. In 1987, Muhammad and Lonnie Ali visited schools, hospitals and mosques in Pakistan, and in 1989 made a pilgrimage to Mecca during Ramadan.

Muhammad Ali, Belinda, and his family arrive in Kinshasa aboard President Mobutu's private plane. There he received praise from most of Zaire as a fan favorite against the undefeated world heavyweight champion George Foreman. Meanwhile, his opponent would keep a low profile prior to their match in what would become known as "The Rumble in the Jungle."

Leading up to his fight with Joe Frazier in the Philippines, the Thrilla in Manila, Muhammad Ali would publicly insult Frazier's intelligence and even sneak into one of his training sessions to verbally harass him from the rafters. Frazier would never forgive him.

In November of 1982, Ali returned to the gym to train for a three-week exhibition tour, with stops planned in Saudi Arabia, India, and Pakistan. However, since retiring, Ali's health, as well as the health of his former boxing assistants, had intensely deteriorated. In 1984, after checking himself into Columbia Presbyterian Hospital, Ali was given a devastating diagnosis: Parkinson's disease.
