Hadith 3351
Narrated Fudalah ibn Ubayd: The Prophet ﷺ was brought a necklace in which there were gold and pearls. (The narrators Abu Bakr and (Ahmad) Ibn Mani' said: The pearls were set with gold in it, and a man bought it for nine or seven dinars. ) The Prophet ﷺ said: (It must not be sold) till the contents are considered separately. The narrator said: He returned it till the contents were considered separately. The narrator Ibn Asa said: By this I intended trade. Abu Dawud said: The word hijarah (stone) was recorded in his note-book before, but he changed it and narrated tijarah (trade).
Hadith 3352
Narrated Fudalah bin Ubaid: At the battle of Khaibar I bought a necklace in which there were gold and pearls for twelve dinars. I separated them and found that its worth was more than twelve dinars. So I mentioned that to the Prophet ﷺ who said: It must not be sold till the contents are considered separately.
Hadith 3353
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.
