To the world, Muhammad Ali was known as the Champ, the Greatest, the People’s Champion. To his children, he’s still known as “The Greatest man who ever lived.” Ali’s daughters Rasheda, Hana, and Laila, and his son Asaad paid tribute to their father on social media after his passing.

“The Greatest Man that ever lived. Daddy my best friend & my Hero You R no longer suffering & now in a better place,” Rasheda tweeted, while Hana called him “Humble Mountain” and “the love of my life.” Laila, in turn, posted a photo of her father and daughter, Sydney. “Thanks for all the love and well wishes,” she wrote on Facebook. “I feel your love and appreciate it.”

Asaad, Ali’s youngest and only son with his fourth wife and widow Lonnie Williams, posted a message to Instagram, “Forever grateful for everything you have ever gave me,” he wrote in part. “You’ve shown me how to love the world in ways I didn’t know possible. You’ve shown me how to be brave and courageous in situations beyond my belief! You’ve taught me so much the last 25 years things that will forever be imprinted in my soul.”

Ali is also survived by daughters Maryum, Jamillah, Miya, and Khaliah, and son Muhammad Ali Jr.
