Narrated Fudalah bin Ubaid: We were with the Messenger of Allah ﷺ at the battle of Khaibar. We were selling to the Jews one uqiyah of gold for one dinar. The narrators other than Qutaibah said: "for two or three dinars. " Then both the versions agreed. The Messenger of Allah ﷺ said: Do not sell gold except with equal weight.
