There is a story told that once a Sufi was healing a child that was ill. He was repeating a few words, and then gave the child to the parents saying, "Now he will be well." Someone who was antagonistic to this said to him, "How can it be possible that be a few words spoken anyone can be healed?" From a mild Sufi an angry answer is never expected, but this time he turned to the man and said, "You understand nothing about it. You are a fool." The man was very much offended. His face was red. He was hot. The Sufi said, "When a word has the power to make you hot and angry, why should not a word have the power to heal?"
