Ali wrote: “We’ve lost a true original. @Prince was someone who cared for others & used his genius to help many.”

‘The Greatest’ had the opportunity to meet ‘the Artist Formerly Known as Prince’ — as he was known at that time — face to face in June of 1997. The two joined forces to promote tolerance and understanding, which were the focus of Ali’s book: HEALING: A Journal of Tolerance and Understanding.

“My friend called me a couple of days ago and asked me. He said, Muhammad wants you to —  and I said ‘Yes.’ I didn’t even let him finish. He could have said ‘mow the lawn,’ and I would have been down with it. Muhammad’s my hero. He has been since I was a child. As you can see, he’s such an inspiration to many people,” Prince said at the press conference with Ali by his side.

Both of these men will always be remembered as royalty.
