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.

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."

To be a great champion you must believe you are the best. If you're not, pretend you are.

The man who views the world at 50 the same as he did at 20 has wasted 30 years of his life.
