“One day, I remember, a dirty glass of water was on a counter and Mr. Muhammad put a clean glass of water beside it. “You want to know how to spread my teachings?” he said, and he pointed to the glasses of water. “Don’t condemn if you see a person has a dirty glass of water,” he said, “just show them the clean glass of water that you have. When they inspect it, you won’t have to say that yours is better.”
