Muhammad bin Muslim bin Tadras محمد بن مسلم بن تدرس أبو الزبير · Commercial Transactions (Kitab Al-Buyu)

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.

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.

The Messenger of Allah (ﷺ) forbade muzabanah, muhaqalah and thunya except it is known.

The Prophet (ﷺ) used to send Abdullah ibn Rawahah (to Khaybar), and he would assess the amount of dates when they began to ripen before they were eaten (by the Jews). He would then give choice to the Jews that they have them (on their possession) by that assessment or could assign to them (Muslims) by that assignment, so that the (amount of) zakat could be calculated before the fruit became eatable and distributed (among the people).

When Allah bestowed Khaybar on His Prophet (ﷺ) as fay' (as a result of conquest without fighting), the Messenger of Allah (ﷺ) allowed (them) to remain there as they were before, and apportioned it between him and them. He then sent Abdullah ibn Rawahah who assessed (the amount of dates) upon them.
