I'm The Greatest, but only in relation to fighting.

I'm a Muslim. I've been a Muslim for 20 years. . . . You know me. I'm a boxer. I've been called the greatest. People recognize me for being a boxer and a man of truth. I wouldn't be here representing Islam if it were terrorist. . . . I think all people should know the truth, come to recognize the truth. Islam is peace.

I knew I had him in the first round. Almighty God was with me. I want everyone to bear witness, I am the greatest! I'm the greatest thing that ever lived. I don't have a mark on my face, and I upset Sonny Liston, and I just turned twenty-two years old. I must be the greatest. I showed the world. I talk to God everyday. I know the real God. I shook up the world, I'm the king of the world. You must listen to me. I am the greatest! I can't be beat!

The woman is the fiber of the nation. She is the producer of life. A nation is only as good as its women.

I predict that this will be the greatest book ever and it will sell more than any other book in history

Do you know why I’m the fastest heavyweight in the world? I’m the only heavyweight that trains underwater!
