Masdad bin Masrhad مسدد بن مسرهد بن مسربل · Commercial Transactions (Kitab Al-Buyu)

The Messenger of Allah (ﷺ) cursed the one who accepted usury, the one who paid it, the witness to it, and the one who recorded it.

The Prophet (ﷺ) forbade selling fruits years ahead, and commanded that unforeseen loss be remitted in respect of what is affected by blight. Abu Dawud said: The attribution of the tradition regarding the effect of blight is one-third of the produce to the Prophet (ﷺ) is not correct. This is the opinion of the people of Medina.

The Messenger of Allah (ﷺ) having said: Allah, Most High, says: "I make a third with two partners as long as one of them does not cheat the other, but when he cheats him, I depart from them."

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.

My uncle sent me and his slave to Sa'id ibn al-Musayyab. We said to him, there is something which has reached us about sharecropping. He replied: Ibn Umar did not see any harm in it until a tradition reached him from Rafi' ibn Khadij. He then came to him and Rafi' told him that the Messenger of Allah (ﷺ) came to Banu Harithah and saw crop in the land of Zuhayr. He said: What an excellent crop of Zuhayr is!…

The Prophet (ﷺ) said: If anyone sows in other people's land without their permission, he has no right to any of the crop, but he may have what it cost him.
