Fadala bin 'Ubaid bin Naqid · Commercial Transactions (Kitab Al-Buyu)

"He said: If these classes differ, sell as you wish if payment is made on the spot."

The Prophet (ﷺ) was brought a necklace in which there were gold and pearls. (The narrators AbuBakr 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:…

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.
