Muhammad Ali’s daughter, Hana Ali, reminisces the final moments of his father after he lost his battle against a respiratory ailment at the HonorHealth Scottsdale Osborn Medical Center in Scottsdale on Friday.

Hana recounted how the iconic three-time world heavyweight boxing champion fought until his last breath. He was a fighter and proved it in the last 30 minutes when his heart just kept beating, although his organs failed. “No one had ever seen anything like it,” wrote Ali’s daughter on a social networking site.

Last Monday, the charismatic boxer fell ill and was immediately admitted to the hospital where his condition gradually deteriorated. Read about his last words and funeral details here.

Ali’s family spokesman Bob Gunnell told reporters Saturday, “You know, Muhammad has battled back many times. We expected it to happen this time.” The boxer was hospitalized several times before on accounts of urinary tract infection in January 2015 and pneumonia in 2014. Each time, he emerged strong and survived his battle for life, states Edition. He was 74 when he succumbed to death at the Phoenix-area hospital last week.

Hana posted touching photos of her with her father when she was a little girl, captioning the photo “Our father was a ‘Humble Mountain!” She also wrote, “Pray for the peace of his beautiful soul and for the happiness of his further journey. God bless you daddy. YOU ARE THE LOVE OF MY LIFE,” according to Today.

On Friday, Ali’s elder daughter Laila Ali also thanked fans on Twitter, sharing a photo of her father with her daughter, Sydney. According to reports, the boxing champion suffered from Parkinson’s for over three decades, a progressive neurological condition that gradually robbed him of his physical dexterity and verbal grace.

While Ali took his last breath, he was surrounded by his children, holding his once powerful hands. They chanted Islamic prayers and hugged and kissed their father. Everyone tried to remain strong, and someone even whispered in his ears, “You can go now. We will be okay. We love you. Thank you. You can go back to God now.” Read about the icon’s top TV moments here.
