The boxing star's dramatic life always grabbed media attention. The public has been witness to a life filled with drama, controversy and thrills including: his court battle to avoid jail for refusing to fight in Vietnam, his three world heavyweight championship wins, his conversion to Islam and his humanitarian work.
Now, he is a national icon celebrating his 70th birthday.
