Mr Ali was hospitalised for a respiratory problem on June 2.
One of the greatest boxers in history, Mr Ali retired in 1981 and soon found signs of sluggishness and neurological damage. He thereafter received treatment for Parkinson's disease.
Mr Ali, known as Cassius Clay before he converted to Islam, began boxing training at the age of 12 years.
He won the World heavyweight championship at the age of 22 in 1964. He again won the title again in 1974 and 1978.
