An Arab who had lost his camel, after searching for it everywhere heard that it was in the stable of the Sherif of Mecca. He went to the Sherif and said, "I have been told that my she-camel which I lost has been sold to you and is in your stable." The Sherif asked him, "How will you recognize your camel? Has she any particular marks?" The Arab said, "She has two black marks upon her heart." The Sherif was amazed to hear this, wondering how the Arab could know about his camel's heart; and in order to ascertain the truth the camel was cut open, and two black marks were found upon her heart. The Sherif asked, "How could you know that your camel had these two black marks upon her heart?" The Arab replied,'Twice my camel was in great sorrow; twice she lost her foal; she looked up and gave a deep sigh, and I knew that each time a black mark was left upon her heart.'
