It is also narrated from Sayyiduna Fadala bin Ubaid, may Allah be pleased with him, he says: We were with the Messenger of Allah, peace and blessings be upon him, on the day of the conquest of Khaybar. The Jews sold an uqiyyah of gold in exchange for two or three dinars, but the Messenger of Allah, peace and blessings be upon him, said: Do not sell gold for gold except that it is equal for equal.
