Zumrah bin Sa‘id Muzani narrates: I heard Sayyiduna Abu Sa‘id Khudri (may Allah be pleased with him) relating a hadith of the Prophet (peace and blessings be upon him) regarding the exchange of gold and silver, on the authority of Sayyiduna ‘Umar (may Allah be pleased with him): Sayyiduna ‘Abdullah bin ‘Umar (may Allah be pleased with them both) came and asked him about this matter; I was present there at that time. Sufyan says: This is the only thing I remember about this matter; it was a hadith similar to what people have narrated from Sayyiduna Abu Sa‘id Khudri (may Allah be pleased with him) from the Prophet (peace and blessings be upon him): "The exchange of gold for gold will be equal, and the exchange of silver for silver will be equal."
