Beside a great fighter in the world, Muhammad Ali also a great speaker. He can talk for hours without making his audience get bored. Some of Muhammad Ali's sayings also very inspirative.
At first, Muhammad Ali join the Nation of Islam lead by Elijah Muhammad which was very racist. Full of hate with white people. Then in 1975, Ali converted to Sunni Islam, the mainstream of Islam along with Warith Deen Muhammad who take over Nation of Islam after the death of Elijah Muhammad.
In 1972 Ali had gone on the Hajj pilgrimage to Mecca. There, just like Malcolm X, meeting people of different colors from all over the world giving him a different outlook and greater spiritual awareness. Ali met people with different colors. Whites, Yellows, Browns, and Blacks all brothers and sisters there. All colors is the same.
