I asked Ibn 'Abbas about the exchange, so he asked: Hand to hand? I replied: Yes. He said: There is no problem. Then I met Abu Sa'eed Al-Khudrei and told him about what Ibn 'Abbas has told me. So, Abu Sa'eed exclaimed: Did he say that?! We will write to him, and he will not be giving you this fatwah [religious verdict]. By Allah, one of the boy-servants of the Messenger of Allah (PBUH) brought some dates, and he did not like it. He said: It is as if these are not from the dates of our land. The boy said: Something had happened to the dates of our land. So I got these dates [in exchange of extra dates of our land]. He said: You exchanged with the double which is an interest. Do not touch this. If you are in doubt [of the quality] of your dates, sell it, then buy whatever dates you want.
