Imam Nafi narrates that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: Do not sell gold for gold and silver for silver except equal for equal; do not increase one thing over the other, and do not sell deferred for immediate, because in such a case I fear usury. Meanwhile, a man narrated to Sayyiduna Ibn Umar (may Allah be pleased with them both) a similar hadith of the Prophet (peace and blessings be upon him) through Sayyiduna Abu Saeed Khudri (may Allah be pleased with him), but before he could finish his statement, Sayyiduna Ibn Umar (may Allah be pleased with them both) reached Sayyiduna Abu Saeed Khudri (may Allah be pleased with him), and I was with him. He entered and said: This person thinks that Sayyiduna Abu Saeed Khudri (may Allah be pleased with him) narrates this hadith from the Messenger of Allah (peace and blessings be upon him). Did you really hear this from the Prophet (peace and blessings be upon him)?
