“This is concerning my question before abu ‘Abd Allah (a.s.), about the case of a people who embark in a ship and buy food and bargain about it. Then one man buys from them. They ask him and he gives them what they ask for of food. So he who collects payment and gives them food becomes the owner of food. He (the Imam) said, ‘It is not harmful. I do not see anything else except that they were partners.’ I then said, ‘The owner of food asks a measuring person who measures for us and we have workers who examine and finds increases and decreases. He (the Imam) said, ‘It is not harmful if errors are not many.’”
