Abu Bakr bin Abi Shayba أبو بكر بن أبي شيبة · Commercial Transactions (Kitab Al-Buyu)

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…

The Messenger of Allah (ﷺ) forbade to sell fresh dates for dry dates when payment is made at a later date. Abu Dawud said: The tradition mentioned above has also been transmitted by Sa'd (b. Abi Waqqas) from the Prophet (ﷺ) through a different chain of narrators in a similar way.

I heard Ibn Umar say: We did not see any harm in sharecropping till I heard Rafi' ibn Khadij say: The Messenger of Allah (ﷺ) has forbidden it. So I mentioned it to Tawus. He said: Ibn Abbas told me that the Messenger of Allah (ﷺ) had not forbidden it, but said: It is better for one of you to lend to his brother than to take a prescribed sum from him.

Ya'la b. Hakim wrote to me: I heard Sulaiman b. Yasar narrating the tradition to the same effect as narrated by 'Ubaid Allah and through the same chain.

I heard the Messenger of Allah (ﷺ) say: If any of you does not leave mukhabarah, he should take notice of war from Allah and His Apostle (ﷺ).

Ibn Rawahah assessed them (the amount of dates) at forty thousand wasqs, and when Ibn Rawahah gave them option, the Jews took the fruits in their possession and twenty thousand wasqs of dates were due from them.
