Abu Nadrah (may Allah have mercy on him) said: I asked Sayyiduna Ibn Abbas (may Allah be pleased with them both) about sarf (the exchange of currency). He asked: "Is the transaction hand to hand (in cash)?" I said: "Yes." He said: "Then there is no harm in it." Abu Nadrah (may Allah have mercy on him) said: Then I met Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) and informed him that I had asked Sayyiduna Ibn Abbas (may Allah be pleased with them both) about sarf and he had said there was no harm in it. Sayyiduna Abu Sa'id (may Allah be pleased with him) said: "Did he really say that? Know that we will soon write to him about this, so that he does not give you such a fatwa." Then he related: By Allah! A young man came to the Messenger of Allah (peace and blessings be upon him) with some dates, and he (peace and blessings be upon him) looked at them with disapproval and asked: "It seems these are not dates of our land?" He said: "There was something wrong with this year's (our) dates, so I (gave those dates and) added something extra on top of them and obtained these dates." At this, the Messenger of Allah (peace and blessings be upon him) said: "You have doubled it; you have dealt in usury (riba). Beware! Do not even go near this. When you find some defect in your dates, first sell them, then (with their price) buy the dates you want to buy."
