Muhammad Ali personally planned his own funeral in the years before his death.
Worshippers and fans of Muhammad Ali have attended a Muslim prayer service to honour the legendary boxer in his hometown of Louisville, Kentucky.
The two-day funeral was planned by Ali in the years before his death, according to foreign media sources.
Ali wanted the Muslim prayer service, known as a Jenazah, to be "a teaching moment", according to Imam Zaid Shakir, who is leading the service.
Muhammad Ali, "The Greatest", died on Friday aged 74.
More than 14,000 people have tickets to the event at the site of Ali's last fight in Louisville in 1961.
American Muslims attending the service and watching on TV said they hoped that the public prayers would help Americans to become more familiar with Islam and its practices.
In 1964, Ali famously converted to Islam, changing his name from Cassius Clay, which he called his "slave name".
