2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Jamil who has said the following: “About the case of a man who buys food, every kur (a certain amount) for a certain price, then prices rise or fall when he has measured only a certain part, and the owner of food refuses to deliver to him the rest, abu ‘Abd Allah عليه السلام, has said, ‘If on the day of purchase he has priced the food and that the food is his, then the remaining food is also his; but if he had only bought without any condition then only what he has paid for is his.’”
