Musnad Abi Ya'la 1325 — Sayyiduna Abu Sa'id al-Khudri came to a man

Abd al-Rahman bin Abi Nu'm (may Allah have mercy on him) narrates that Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) came to a man and asked him: "Have you read what we have not read, or have you had a companionship that we were not granted?" He said: "I have read only what you have read, and the honour of the companionship of the Messenger (peace and blessings be upon him) was yours." He (may Allah be pleased with him) said: "Then on what basis do you give people the fatwa that two dirhams may be exchanged for three dirhams, and one dirham for two dirhams?" Then Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Gold for gold, like for like; whatever is added is usury (riba). And silver for silver, like for like; whatever is added is usury." The narrator said: After that I heard that man supplicating: 'Allahumma inni atubu ilayka mimma kuntu ufti bihi al-nasa fi al-sarf' (O Allah, I repent to You from the fatwas I used to give people about currency exchange).
