No one was closer to Muhammad Ali than Rahaman, his only sibling and best friend. The brothers lived together, trained together and shared pivotal experiences, from Ali's time in the Nation of Islam to the iconic 'Rumble in the Jungle' against George Foreman. Rahaman became Ali's best sparring partner and part of his inner circle, also acting as a personal bodyguard throughout his brother's career. Rahaman retired from competing as a heavyweight himself in 1972, with a record of fourteen wins, three losses and one draw.
