Legendary boxer Muhammad Ali, 71, is not expected to live through the summer, and could possibly die within days, according to his brother, Rahman Ali.

“He’s in a bad way,” Rahman said in an interview. “He’s very sick, It could be months, it could be days. I don’t know if he’ll last the summer. He’s in God’s hands.”

Rahman says that the former heavyweight champion no longer recognizes him and is unable to speak. Ali was diagnosed with Parkinson’s disease in 1984 but remained active for many years and made a moving appearance at the Atlanta 1996 Olympic Games where he lit the flame.

Though Ali’s wife has not commented on the claims, Rahman says that his brother has requested a quote from Dr. Martin Luther King, Jr. be inscribed on his headstone: “I tried to love somebody, I did try to feed the hungry. I did try, in my life, to clothe those who were naked. I want you to say that I tried to love and serve humanity.’ The Greatest.”
