He said, "You are asking me for informationabout a bewitched woman. A slavegirl of hers has bewitched her." 'A'ishawas told and asked the girl, "Have you put a spell on me?" "Yes," she replied."Why?' she asked. "Because you will never free me," she answered. Then'A'isha said, "Sell her to the worst masters among the Arabs."
