“A man during the time of ’Amir al-Mu’minin (a.s.), had found a treasure and my father bought it from him for three hundred dirham and one hundred sheep followed by their young; and my mother blamed him for it, saying, ‘You have bought it for three hundred sheep; one hundred of their young, one hundred sheep and one hundred in their womb.’ My father regretted and went to ask for a reduced price. He refused and said, ‘Take from me ten sheep, take from me twenty sheep’ and made him tired. My father then took the treasure and made a price for one thousand sheep from it. The other man came back and said, ‘Take your sheep back and give me whatever you like.’ But he refused. He tried until he was exhausted and said, ‘I can harm you.’ He complained before ’Amir al-Mu’minin (a.s.), against my father. When my father told his side of the story before ’Amir al- Mu’minin (a.s.), he (the Imam) said to the owner of treasure, ‘Pay one-fifth of what you have received because it is on you as the finder of the treasure and there is nothing on him because he has taken the price of his sheep.’”
