Muhammad Ali’s daughter, Hana Ali, has opened up on what it was like during her father’s final moments.
Muhammad Ali’s family thought he would pull through when he was admitted to hospital with respiratory problems.
The boxing great died aged 74 on Saturday surrounded by close relatives after spending five days in hospital.
His official cause of death was septic shock as a result of unspecified natural causes.
His daughter Hana Ali revealed her father’s heart “kept on beating for 30 minutes” after all his organs failed.
She wrote on Twitter: “No one had ever seen anything like it. A true testament to the strength of his spirit and will!”
Speaking about his final moments, Hana said: “The whole family tried to stay strong and whispered in his ear, “You can go now. We will be okay.
“We love you. Thanks you. You can go back to God now.”
“All of us were around him hugging and kissing him and holding hands, chanting the Islamic prayer.”
Family spokesman Bob Gunnell said: “Muhammad became ill on Monday and was admitted to hospital on Monday night.
“But he was in fair condition and we expected that to stay the case.
“Muhammad has beaten back many times and we expected that to happen this time, but the family was called when it became more serious.”
Mr Gunnell said Ali did not suffer in his final moments and that his family had a whole day to say their goodbyes to him.
“The champ would have been proud of his family,” he added.
