A story is told about a man who went to the Sharif of Mecca and said to him that the camel the Sharif rode was his and had been stolen from him. The Sharif asked whether he had any witnesses. He had none. Then the Sharif asked, "What proof have you that the camel is really yours? How can you recognize it?" The man answered, "On my camel's heart are two black spots." "On its heart?", said the Sharif, "How do you know that?" The man replied, "The animals feel as we do. My camel - it is a she-camel - had two young ones, and at different times both died. Each time I saw that the camel looked up to heaven and gave a cry like a sigh, a deep great sigh, and that was all. So I know that on her heart are two black spots." The Sharif held out two gold coins and said, "Either take back your camel, or take the price for your discovery." If the heart of an animal can feel like this, how much can the heart of man feel!
