“Abu ‘Abd Allah (a.s.), has said that once two men presented their case before Amir al- Mu’minin, Ali (a.s.), about a stumper in their hand and each presented testimony that it was bred in his facilities. He (the Imam) then asked them to take an oath. One party did not take oath, then he (the Imam) issued a judgment in favor of the one who had taken the oath. It then was asked, ‘What would have happened if it was not in the hand of anyone of them and both presented testimony?’ He (the Imam) said, ‘I would ask them to take an oath. If one party took the oath and the other refused, the one who took the oath wins the case. If both of them took oath I will make it for them half and half.’ It then was asked, ‘What happens if it is in the hand of one of them and they both present testimony?’ He (the Imam) said, ‘I would issue a judgment in favor of the one who has it in his hand and takes an oath.’”
