Narrated Abu Rafi: The Messenger of Allah ﷺ borrowed a young camel, and when the camels of the sadaqah (alms) came to him, he ordered me to pay the man his young camel. I said: I find only an excellent camel in its seventh year. So the Prophet ﷺ said: Give it to him, for the best person is he who discharges his debt in the best manner.

Narrated Jabir ibn Abdullah: The Prophet ﷺ owed me a debt and gave me something extra when he paid it.

Narrated Umar: The Messenger of Allah ﷺ as saying: Gold for gold is interest unless both hand over on the spot ; wheat for wheat is interest unless both hand over on the spot ; dates for dates is interest unless both hand over on the spot ; barley for barley is interest unless both hand over on the spot.

Narrated Ubadah ibn as-Samit: The Messenger of Allah ﷺ said: Gold is to be paid for with gold, raw and coined, silver with silver, raw and coined (in equal weight), wheat with wheat in equal measure, barley with barley in equal measure, dates with dates in equal measure, salt by salt with equal measure; if anyone gives more or asks more, he has dealt in usury. But there is no harm in selling gold for silver and silver (for gold), in unequal weight, payment being made on the spot. Do not sell them if they are to be paid for later. There is no harm in selling wheat for barley and barley (for wheat) in unequal measure, payment being made on the spot. If the payment is to be made later, then do not sell them. Abu Dawud said: This tradition has also been transmitted by Saeed bin Abi 'Arubah, Hisham al-Dastawa'i and Qatadah from Muslim bin Yasar through his chain.

The tradition mentioned above has also been transmitted by Ubadah bin al-Samit through a different chain of transmitters with some alternation. This version adds: "He said: If these classes differ, sell as you wish if payment is made on the spot. "

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).

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.

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.

Narrated Abdullah ibn Umar: I used to sell camels at al-Baqi for dinars and take dirhams for them, and sell for dirhams and take dinars for them. I would take these for these and give these for these. I went to the Messenger of Allah ﷺ who was in the house of Hafsah. I said: Messenger of Allah, take it easy, I shall ask you (a question): I sell camels at al-Baqi'. I sell (them) for dinars and take dirhams and I sell for dirhams and take dinars. I take these for these, and give these for these. The Messenger of Allah ﷺ then said: There is no harm in taking them at the current rate so long as you do not separate leaving something to be settled.

The tradition mentioned above has also been transmitted by Simak (b. Harb) with a different chain of narrators and to the same effect. The first version is more perfect. It does not mention the words "at the current rate".
