Qutayba bin Sa'id bin Jamil قتيبة بن سعيد بن جميل · Commercial Transactions (Kitab Al-Buyu)

The Messenger of Allah (ﷺ) would not say funeral prayer over a person who died while the debt was due from him. A dead Muslim was brought to him and he asked: Is there any debt due from him? They (the people) said: Yes, two dirhams. He said: Pray yourselves over your companion. Then AbuQatadah al-Ansari said: I shall pay them, Messenger of Allah.

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.

The Messenger of Allah (ﷺ) commanded him to equip an army, but the camels were insufficient. So he commanded him to keep back the young camels of sadaqah, and he was taking a camel to be replaced by two when the camels of sadaqah came.

I asked Rafi' b. Khadij about the lease of land for gold and silver (i.e. for dinars and dirhams). There is no harm in it, for the people used to let out land in the time of the Messenger of Allah (ﷺ) for what grew by the current of water and at the banks of streamlets and at the places of cultivation. So sometimes this (portion) perished and that (portion) was saved, and sometimes this remained intact and that perished.…

Rafi' had cultivated a land. The Prophet (ﷺ) passed him when he was watering it. So he asked him: To whom does the crop belong, and to whom does the land belong? He replied: The crop is mine for my seed and labour. The half (of the crop) is mine and the half for so-and-so. He said: You conducted usurious transaction. Return the land to its owner and take your wages and cost.

The Messenger of Allah (ﷺ) made an agreement with the people of Khaibar to work and cultivate in return for half of the fruits or produce.
