This is the story of Baba Abdallah. The plot explores the dangers of being in greed. Orphan from a young age, Baba achieved success through camel-renting business. One day, he met a dervish who reveals Baba a secret about hidden wealth that could make both of them richer. That dervish took Baba to the treasure in exchange of his forty camels. Baba agreed. They then loaded the camels with all treasure they could carry. But, while on his journey back home, Abdallah was struck with greed for more. He then asked the dervish a few camels back so he can bring more treasure; the dervish agreed. But, unfortunately, the voracious nature took over Baba and he then wanted to possess the magical ointment too. The dervish warned him not to use the ointment as he might go blind, but, drenched in greed, Baba disobeys and lost his right eye. His greedy nature made him blind as well as poor because he was not even able to continue his business.
