Muhammad Ali

A man who views the world the same at fifty as he did at twenty has wasted thirty years of his life.

He who is not courageous enough to take risks will accomplish nothing in life.

I hated every minute of training, but I said, 'Don't quit. Suffer now and live the rest of your life as a champion.'

Old age is just a record of one's whole life.

If you even dream of beating me you'd better wake up and apologize.

I wanted to use my fame and this face that everyone knows so well to help uplift and inspire people around the world.

I should be a postage stamp, because that's the only way I'll ever get licked. I'm beautiful. I'm fast. I'm so mean I make medicine sick. I can't possibly be beat.

I done wrestled with an alligator, I done tussled with a whale; handcuffed lightning, thrown thunder in jail; only last week, I murdered a rock, injured a stone, hospitalised a brick; I'm so mean I make medicine sick.

You can't keep your mind on fighting when you're thinking about a woman. You can't keep your concentration. You feel like sleeping all the time.

I'm just hoping that people understand that Islam is peace and not violence.

The word 'Islam' means 'peace.' The word 'Muslim' means 'one who surrenders to God.' But the press makes us seem like haters.

When you can whip any man in the world, you never know peace.
