Liberal American Rabbi Michael Lerner has been invited to speak at boxing legend Muhammad Ali’s funeral.

“I am deeply humbled and honoured to be invited to speak at Muhammad Ali’s funeral,” Lerner, the editor of Tikkun Magazine, wrote on Facebook.

The funeral is scheduled for Friday in Louisville, KY. Ali died last Friday at 74. He had Parkinson’s disease for more than 30 years.

Jewish actor-comedian Billy Crystal, who is know for his imitation of Ali, will also speak at the funeral, along with representatives of Islam, Christianity, Buddhism, Mormonism and Catholicism. Former U.S. President Bill Clinton will deliver a eulogy. Other speakers include Ali’s wife, Lonnie; his daughter Maryum, and sportscaster Bryant Gumbel.

Turkish President Recep Tayyip Erdogan and King Abdullah II of Jordan reportedly had been scheduled to speak at the ceremony and then were removed from the program due to the number of speakers.

The ceremony will be led by California imam and scholar Zaid Shakir. Jenazah, a traditional Muslim funeral service, will be held Thursday.

Lerner’s Tikkun reported that the Ali family member who called the rabbi to ask him to participate in the memorial ceremony told him that Muhammad Ali and his wife “had been fans of his for many, many years.” Lerner said he had not heard from Ali since 1995, when the boxer sent him a note to commend him on the book he wrote with Cornel West titled Jews and Blacks: Let the Healing Begin.
