Sa'id bin Myna سعيد بن مينا · Commercial Transactions (Kitab Al-Buyu)

The Messenger of Allah (ﷺ) forbade to sell spoils of war till they are appointed, and to sell palm trees till they are safe from every blight, and a man praying without tying belt.

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 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.
