Mourners of All Faiths Attend Traditional Muslim Funeral for Muhammad AliThousands of people — black and white, Muslims and Jews, old and young — packed Freedom Hall in Louisville, Kentucky, Thursday for a traditional Muslim funeral for Muhammad Ali. The boxing legend, who was known by billions around the world, died last week at age 74 after a long fight against Parkinson's disease. His service was held in the same place in Ali's hometown where he fought his first professional match in 1960, shortly after his gold medal triumph at the Summer Olympics in Rome. In the Islamic tradition, Muslim men and woman prayed in separate groups as Imam Zaid Shakir led the service. "This is about ... sending him off in the very best of fashion and honor his memory, live his memory and love each other as he would wish," the imam preached. Worshippers and admirers called Ali the true face of Islam — one that promotes peace and tolerance of people of all faiths.

Former President Bill Clinton and comedian Billy Crystal, whose accurate impersonation of Ali often left the champ doubled over with laughter, will deliver eulogies. Senior White House adviser Valerie Jarrett will read a letter from U.S. President Barack Obama, who will remain in Washington to attend his daughter's high school graduation. The service will be televised live. Ali was born Cassius Clay, but he cast off what he called a "slave name" when he embraced Islam in 1964. His conversion came with a price. Many sportswriters and the conservative boxing community were slow to embrace his new name, and still called him Clay well into the late 1960s, infuriating him. Ali also refused induction into the U.S. Army during the Vietnam War because of his faith, saying he had "no quarrel" with the Viet Cong. This cost him his heavyweight titles in 1967, and he was banned from professional boxing until the Supreme Court overturned the ban in 1971.
