The former world heavyweight boxing champion, one of the world's best-known sportsmen, died at a hospital in the US city of Phoenix in Arizona state after being admitted on Thursday.
He was suffering from a respiratory illness, a condition that was complicated by Parkinson's disease.
The funeral will take place in Ali's hometown of Louisville, Kentucky, his family said in a statement.

Very sad.
Personally, his boxing career doesn't interest me much. His greatness, I think, lies in his political activism, which is generally played down.
