Allah is the Greatest. I'm just the greatest boxer.

When a chivalrous man makes an oath, he is faithful to it, and when he attains power, he spares his enemy.

My definition of evil is unfriendliness.

I always bring out the best in men I fight, but Joe Frazier, I'll tell the world right now, brings out the best in me. I'm gonna tell ya, that's one helluva man, and God bless him

Success is not achieved by winning all the time. Real success comes when we rise after we fall.

Superman don't need no seat belt.

God will not place a burden on a man's shoulders knowing that he cannot carry it.
