مسند امام احمد بن حنبل · Hadith 314
It was narrated that Malik bin Aws bin al-Hadathan said: I brought some dinars of mine and wanted to exchange them. Talhah bin 'Ubaidullah met me and we agreed to an exchange. Then he took them and said: Wait until my storekeeper comes - Abu 'Amir said: From al-Ghabah (a place). And he said concerning it: All of it should be 'Take this' and 'take this' [i.e., exchanged on the spot]. I asked 'Umar bin al-Khattab (RA) about that and he said: I heard the Messenger of Allah (PBUH) say: "Silver for gold is rciw, unless it is exchanged on the spot; wheat for wheat is riba, unless it is exchanged on the spot; barley for barley is riba, unless it is exchanged on the spot; dates for dates is riba unless it is exchanged on the spot."
