Question
There is a fatwa that says: It is not permissible to exchange olives for oil; rather, it is necessary to introduce cash in their exchange to avoid usury, because olives are the source of oil. How accurate is this fatwa?
Answer
I say, and with God's success: it is permissible to exchange olives for oil if the amount of oil in the olives is estimated, and then we proceed with the exchange based on this estimation, and God knows best.
